A short biography who invented zero

What is the Origin of Zero in India?
Zero is a symbol for the concept of nothing or having nothing. Now a day’s zero both as a numeric symbol and a concept help us to do calculus, in solving complicated equations and is the basis of computer. This article deals with the invention of Zero in India, how and when it took place.

The discovery of Zero is the greatest abstraction of the human mind. It is not wrong to say that the concept or the invention of zero was revolutionary in mathematics. Zero is a symbol for the concept of nothingness or having nothing. It gives rise the ability for a common person to be able to do mathematics isn’t. Before it, mathematicians struggled to perform the simplest arithmetic calculations. Now a day’s zero both as a numeric symbol and a concept help us to do calculus, in solving complicated equations and is the basis of a computer.

In mathematics it is really vibrant in the Indian subcontinent. First place to see the ideally zero beginning to be born is from Bakhshali manuscript dating back to the third or fourth century. It is said that a farmer in 1881 dug up the text from a field in the Bakhshali village near Peshawar today is Pakistan. It is quite a complicated document because it is not just a one piece of document, but it consists of many pieces written over a pace quite a century back. With the help of radiocarbon dating technique, which is a method for measuring the content of carbon isotopes in organic material to determine its age shows that the Bakhshali manuscript consists of several texts. The oldest part dated to AD 224-383, next is to AD 680-779 and another is to AD 885-993. This manuscript has 70 leaves of birch bark and contains hundreds of zeros in the form of dots.

Who created the first map of India

That time these dots were not zero as a number, but it was used as a placeholder digit for building large numbers like 101, 1100 etc. Even with the help of this document merchants in the past do calculations. Some more ancient cultures are there which used the similar placeholders like the Babylonians, they used it as a double wedge, Mayans, used it as the number of shells. So, we can say that ancient civilizations knew the concept of ‘nothing’ but they don’t have the symbol or letter for it. According to the Oxford University, in India, in Gwalior an inscription was found in a temple which dates back to the ninth century and has been considered the oldest recorded example of a zero.

mathematicians-pythagoras


Pythagoras (circa 570-495BC)



Vegetarian mystical leader and number-obsessive, he owes his standing as the most famous name in maths due to a theorem about right-angled triangles, although it now appears it probably predated him. He lived in a community where numbers were venerated as much for their spiritual qualities as for their mathematical ones. His elevation of numbers as the essence of the world made him the towering primogenitor of Greek mathematics, essentially the beginning of mathematics as we know it now. And, famously, he didn't eat beans.

Hypatia (cAD360-415)

Mathematician-Hypatia

Women are under-represented in mathematics, yet the history of the subject is not exclusively male. Hypatia was a scholar at the library in Alexandria in the 4th century CE. Her most valuable scientific legacy was her edited version of Euclid's The Elements, the most important Greek mathematical text, and one of the standard versions for centuries after her particularly horrific death: she was murdered by a Christian mob who stripped her naked, peeled away her flesh with broken pottery and ripped apart her limbs.

Girolamo Cardano (1501 -1576)


mathematician-girolamo-cardano


Italian polymath for whom the term Renaissance man could have been invented. A doctor by profession, he was the author of 131 books. He was also a compulsive gambler. It was this last habit that led him to the first scientific analysis of probability. He realised he could win more on the dicing table if he expressed the likelihood of chance events using numbers. This was a revolutionary idea, and it led to probability theory, which in turn led to the birth of statistics, marketing, the insurance industry and the weather

Narendra Modi


Narendra Damodardas Modi (Gujarati pronunciation: [; born 17 September 1950) is an Indian politician serving as the 14th and current Prime Minister of India since 2014. He was the Chief Minister of Gujarat from 2001 to 2014 and is the Member of Parliament for Varanasi. Modi is a member of the Bharatiya Janata Party (BJP) and of the Rashtriya Swayamsevak Sangh (RSS), a Hindu nationalist volunteer organisation. He is the first prime minister outside of the Indian National Congress to win two consecutive terms with a full majority and the second to complete five years in office after Atal Bihari Vajpayee.[2]
Born to a Gujarati family in Vadnagar, Modi helped his father sell tea as a child and has said he later ran his own stall. He was introduced to the RSS at the age of eight, beginning a long association with the organisation. Modi left home after finishing high-school in part due to an arranged arriage to Jashodaben Chimanlal, which he abandoned and publicly acknowledged only many decades later. Modi travelled around India for two years and visited a number of religious centres before returning to Gujarat. In 1971 he became a full-time worker for the RSS. During the state of emergency imposed across the country in 1975, Modi was forced to go into hiding. The RSS assigned him to the BJP in 1985 and he held several positions within the party hierarchy until 2001, rising to the rank of general secretary.Shri Narendra Modi.jpg
Modi was appointed Chief Minister of Gujarat in 2001 due to Keshubhai Patel's failing health and poor public image following the earthquake in Bhuj. Modi was elected to the legislative assembly soon after. His administration has been considered complicit in the 2002 Gujarat riots[a] or otherwise criticised for its handling of it. A Supreme Court-appointed Special Investigation Team found no evidence to initiate prosecution proceedings against Modi personally.[b] His policies as chief minister, credited with encouraging economic growth, have received praise.[10] His administration has been criticised for failing to significantly improve health, poverty and education indices in the state.[c]
Modi led the BJP in the 2014 general election which gave the party a majority in the Indian lower house of parliament, the Lok Sabha, the first time for any single party since 1984. Modi's administration has tried to raise foreign direct investment in the Indian economy and reduced spending on healthcare and social welfare programmes. Modi has attempted to improve efficiency in the bureaucracy; he has centralised power by abolishing the Planning Commission. He began a high-profile sanitation campaign and weakened or abolished environmental and labour laws. He initiated a controversial demonetisation of high-denomination banknotes.
Following his party's victory in the 2019 general election, his administration revoked the special status of Jammu and Kashmir. His administration also introduced the Citizenship Amendment Act, which resulted in widespread protests across the country. Described as engineering a political realignment towards right-wing politics, Modi remains a figure of controversy domestically and internationally over his Hindu nationalist beliefs and his role during the 2002 Gujarat riots, cited as evidence of an exclusionary social agenda. 

Early life and education

Narendra Modi was born on 17 September 1950 to a family of grocers in VadnagarMehsana districtBombay State (present-day Gujarat). He was the third of six children born to Damodardas Mulchand Modi (c. 1915–1989) and Hiraben Modi (born c. 1920).[19] Modi's family belonged to the Modh-Ghanchi-Teli (oil-presser) community,[20][21][22] which is categorised as an Other Backward Class by the Indian government.[23][24]
As a child, Modi helped his father sell tea at the Vadnagar railway station, and said that he later ran a tea stall with his brother near a bus terminus.[25] Modi completed his higher secondary education in Vadnagar in 1967, where a teacher described him as an average student and a keen debater, with interest in theatre.[26] Modi had an early gift for rhetoric in debates, and his teachers and students noted this.[27] Modi preferred playing larger-than-life characters in theatrical productions, which has influenced his political image.[28][29]
When eight years old, Modi discovered the Rashtriya Swayamsevak Sangh (RSS) and began attending its local shakhas (training sessions). There, Modi met Lakshmanrao Inamdar, popularly known as Vakil Saheb, who inducted him as a balswayamsevak (junior cadet) in the RSS and became his political mentor.[30] While Modi was training with the RSS, he also met Vasant Gajendragadkar and Nathalal Jaghda, Bharatiya Jana Sangh leaders who were founding members of the BJP's Gujarat unit in 1980.[31]
Also in Narendra Modi's childhood, in a custom traditional to his caste, his family arranged a betrothal to a girl, Jashodaben Chimanlal Modi, leading to their marriage when they were teenagers.[32][33] Sometime thereafter, he abandoned the further marital obligations implicit in the custom,[34] and left home, the couple going on to lead separate lives, neither marrying again, and the marriage itself remaining unmentioned in Modi's public pronouncements for many decades.[35] In April 2014, shortly before the national elections that swept him to power, Modi publicly affirmed that he was married and his spouse was Jashodaben; the couple has remained married, but estranged.[36]
Modi spent the ensuing two years travelling across Northern and North-eastern India, though few details of where he went have emerged.[37] In interviews, Modi has described visiting Hindu ashrams founded by Swami Vivekananda: the Belur Math near Kolkata, followed by the Advaita Ashrama in Almora and the Ramakrishna Mission in Rajkot. Modi remained only a short time at each, since he lacked the required college education.[38][39][40] Vivekananda has been described as a large influence in Modi's life.[41]
In the early summer of 1968, Modi reached the Belur Math but was turned away, after which Modi wandered through Calcutta, West Bengal and Assam, stopping in Siliguri and Guwahati.[42] Modi then went to the Ramakrishna Ashram in Almora, where he was again rejected, before travelling back to Gujarat via Delhi and Rajasthan in 1968–69.[43] Sometime in late 1969 or early 1970, Modi returned to Vadnagar for a brief visit before leaving again for Ahmedabad.[44] There, Modi lived with his uncle, working in the latter's canteen at the Gujarat State Road Transport Corporation.[45][46]
In Ahmedabad, Modi renewed his acquaintance with Inamdar, who was based at the Hedgewar Bhavan (RSS headquarters) in the city.[47][48][49] After the Indo-Pakistani War of 1971, he stopped working for his uncle and became a full-time pracharak (campaigner) for the RSS,[46] working under Inamdar.[50] Shortly before the war, Modi took part in a non-violent protest against the Indian government in New Delhi, for which he was arrested; this has been cited as a reason for Inamdar electing to mentor him.[50] Many years later Modi would co-author a biography of Inamdar, published in 2001.[51]
In 1978 Modi received a Bachelor of Arts degree in political science from School of Open Learning[52] at University of Delhi,[53][54] graduating with a third class.[55] Five years later, in 1983, he received a Master of Arts degree in political science from Gujarat University, graduating with a first class[56][57] as an external distance learning student.[58]

Early political career

In June 1975, Prime Minister Indira Gandhi declared a state of emergency in India which lasted until 1977. During this period, known as "The Emergency", many of her political opponents were jailed and opposition groups were banned.[59][60] Modi was appointed general secretary of the "Gujarat Lok Sangharsh Samiti", an RSS committee co-ordinating opposition to the Emergency in Gujarat. Shortly afterwards, the RSS was banned.[61] Modi was forced to go underground in Gujarat and frequently travelled in disguise to avoid arrest. He became involved in printing pamphlets opposing the government, sending them to Delhi and organising demonstrations.[62][63] Modi was also involved with creating a network of safe houses for individuals wanted by the government, and in raising funds for political refugees and activists.[64] During this period, Modi wrote a book in GujaratiSangharsh Ma Gujarat (In The Struggles of Gujarat), describing events during the Emergency.[65][66] Among the people he met in this role was trade unionist and socialist activist George Fernandes, as well as several other national political figures.[67] In his travels during the Emergency, Modi was often forced to move in disguise, once dressing as a monk, and once as a Sikh.[64]
Modi became an RSS sambhag pracharak (regional organiser) in 1978, overseeing RSS activities in the areas of Surat and Vadodara, and in 1979 he went to work for the RSS in Delhi, where he was put to work researching and writing the RSS's version of the history of the Emergency.[68] He returned to Gujarat a short while later, and was assigned by the RSS to the BJP in 1985.[31] In 1987 Modi helped organise the BJP's campaign in the Ahmedabad municipal election, which the BJP won comfortably; Modi's planning has been described as the reason for that result by biographers.[69] After L. K. Advani became president of the BJP in 1986, the RSS decided to place its members in important positions within the BJP; Modi's work during the Ahmedabad election led to his selection for this role, and Modi was elected organising secretary of the BJP's Gujarat unit later in 1987.[70]
Modi rose within the party and was named a member of the BJP's National Election Committee in 1990, helping organise L. K. Advani's 1990 Ram Rath Yatra in 1990 and Murli Manohar Joshi's 1991–92 Ekta Yatra (Journey for Unity).[26][71][72] However, he took a brief break from politics in 1992, instead establishing a school in Ahmedabad; friction with Shankersingh Vaghela, a BJP MP from Gujarat at the time, also played a part in this decision.[72] Modi returned to electoral politics in 1994, partly at the insistence of Advani, and as party secretary, Modi's electoral strategy was considered central to the BJP victory in the 1995 state assembly elections.[72][31][73][74] In November of that year Modi was elected BJP national secretary and transferred to New Delhi, where he assumed responsibility for party activities in Haryana and Himachal Pradesh.[73][75] The following year, Shankersinh Vaghela, a prominent BJP leader from Gujarat, defected to the Indian National Congress (Congress, INC) after losing his parliamentary seat in the Lok Sabha elections.[26] Modi, on the selection committee for the 1998 Assembly elections in Gujarat, favoured supporters of BJP leader Keshubhai Patel over those supporting Vaghela to end factional division in the party. His strategy was credited as key to the BJP winning an overall majority in the 1998 elections,[73][76] and Modi was promoted to BJP general secretary (organisation) in May of that year.[77]

Chief Minister of Gujarat

Taking office

In 2001, Keshubhai Patel's health was failing and the BJP lost a few state assembly seats in by-elections. Allegations of abuse of power, corruption and poor administration were made, and Patel's standing had been damaged by his administration's handling of the earthquake in Bhuj in 2001.[73][78][79] The BJP national leadership sought a new candidate for the chief ministership, and Modi, who had expressed misgivings about Patel's administration, was chosen as a replacement.[26] Although BJP leader L. K. Advani did not want to ostracise Patel and was concerned about Modi's lack of experience in government, Modi declined an offer to be Patel's deputy chief minister, telling Advani and Atal Bihari Vajpayee that he was "going to be fully responsible for Gujarat or not at all". On 3 October 2001 he replaced Patel as Chief Minister of Gujarat, with the responsibility of preparing the BJP for the December 2002 elections.[80] Modi was sworn in as Chief Minister on 7 October 2001,[81] and entered the Gujarat state legislature on 24 February 2002 by winning a by-election to the Rajkot – II constituency, defeating Ashwin Mehta of the INC by 14,728 votes.[82]

2002 Gujarat riots

On 27 February 2002, a train with several hundred passengers burned near Godhra, killing approximately 60 people.[e] The train carried a large number of Hindu pilgrims returning from Ayodhya after a religious ceremony at the site of the demolished Babri Masjid.[85][86] In making a public statement after the incident, Modi declared it a terrorist attack planned and orchestrated by local Muslims.[5][85][87] The next day, the Vishwa Hindu Parishad called for a bandh across the state.[88][89] Riots began during the bandh, and anti-Muslim violence spread through Gujarat.[85][88][89] The government's decision to move the bodies of the train victims from Godhra to Ahmedabad further inflamed the violence.[85][90] The state government stated later that 790 Muslims and 254 Hindus were killed.[91] Independent sources put the death toll at over 2000.[85][92] Approximately 150,000 people were driven to refugee camps.[93] Numerous women and children were among the victims; the violence included mass rapes and mutilations of women.[4][94]
The government of Gujarat itself is generally considered by scholars to have been complicit in the riots,[3][4][5] and has otherwise received heavy criticism for its handling of the situation.[95] Several scholars have described the violence as a pogrom, while others have called it an example of state terrorism.[96][97][98] Summarising academic views on the subject, Martha Nussbaum said: "There is by now a broad consensus that the Gujarat violence was a form of ethnic cleansing, that in many ways it was premeditated, and that it was carried out with the complicity of the state government and officers of the law."[4] The Modi government imposed a curfew in 26 major cities, issued shoot-at-sight orders and called for the army to patrol the streets, but was unable to prevent the violence from escalating.[88][89] The president of the state unit of the BJP expressed support for the bandh, despite such actions being illegal at the time.[5] State officials later prevented riot victims from leaving the refugee camps, and the camps were often unable to meet the needs of those living there.[99] Muslim victims of the riots were subject to further discrimination when the state government announced that compensation for Muslim victims would be half of that offered to Hindus, although this decision was later reversed after the issue was taken to court.[100] During the riots, police officers often did not intervene in situations where they were able.[4][87][101] In 2012 Maya Kodnani, a minister in Modi's government from 2007 to 2009, was convicted by a lower court for participation in the Naroda Patiya massacre during the 2002 riots.[102][103] Although Modi's government had announced that it would seek the death penalty for Kodnani on appeal, it reversed its decision in 2013.[104][105] On 21 April 2018, the Gujarat High Court acquitted Kodnani while noting that there were several shortfalls in the investigation.[106]
Modi's personal involvement in the 2002 events has continued to be debated. During the riots, Modi said that "What is happening is a chain of action and reaction."[4] Later in 2002, Modi said the way in which he had handled the media was his only regret regarding the episode.[107] In March 2008, the Supreme Court reopened several cases related to the 2002 riots, including that of the Gulbarg Society massacre, and established a Special Investigation Team (SIT) to look into the issue.[95][108][109] In response to a petition from Zakia Jafri (widow of Ehsan Jafri, who was killed in the Gulbarg Society massacre), in April 2009 the court also asked the SIT to investigate the issue of Modi's complicity in the killings.[108] The SIT questioned Modi in March 2010; in May, it presented to the court a report finding no evidence against him.[108][110] In July 2011, the court-appointed amicus curiae Raju Ramachandran submitted his final report to the court. Contrary to the SIT's position, he said that Modi could be prosecuted based on the available evidence.[111][112] The Supreme Court gave the matter to the magistrate's court. The SIT examined Ramachandran's report, and in March 2012 submitted its final report, asking for the case to be closed. Zakia Jaffri filed a protest petition in response. In December 2013 the magistrate's court rejected the protest petition, accepting the SIT's finding that there was no evidence against the chief minister.[113]

2.Donald Trump
PRESIDENT OF THE UNITED STATES
WRITTEN BY: akshat kaushik
LAST UPDATED:  See Article History

Donald Trump, in full Donald John Trump, (born June 14, 1946, New York, New York, U.S.), 45th president of the United States (2017– ). Trump was a real-estate developer and businessman who owned, managed, or licensed his name to several hotelscasinos, golf courses, resorts, and residential properties in the New York City area and around the world. From the 1980s Trump also lent his name to scores of retail ventures—including branded lines of clothing, cologne, food, and furniture—and to Trump University, which offered seminars in real-estate education from 2005 to 2010. In the early 21st century his private conglomerate, the Trump Organization, comprised some 500 companies involved in a wide range of businesses, including hotels and resorts, residential properties, merchandise, and entertainment and television. In 2019 Trump became only the third president in U.S. history (after Andrew Johnson in 1868 and Bill Clinton in 1998) to be impeached by the U.S. House of Representatives. He was also the first president to be impeached during his first term of office.


Early Life And Business Career
Trump was the fourth of five children of Frederick (Fred) Christ Trump, a successful real estate developer, and Mary MacLeod. Donald’s eldest sister, Maryanne Trump Barry, eventually served as a U.S. district court judge (1983–99) and later as a judge on the U.S. Court of Appeals for the Third Circuit until her retirement in 2011. His elder brother, Frederick, Jr. (Freddy), worked briefly for his father’s business before becoming an airline pilot in the 1960s. Freddy’s alcoholism led to his early death in 1981, at the age of 43.


 

 Beginning in the late 1920s, Fred Trump built hundreds of single-family houses and rowhouses in the Queens and Brooklyn boroughs of New York City, and from the late 1940s he built thousands of apartment units, mostly in Brooklyn, using federal loan guarantees designed to stimulate the construction of affordable housing. During World War II he also built federally backed housing for naval personnel and shipyard workers in Virginia and Pennsylvania. In 1954 Fred was investigated by the Senate Banking Committee for allegedly abusing the loan-guarantee program by deliberately overestimating the costs of his construction projects to secure larger loans from commercial banks, enabling him to keep the difference between the loan amounts and his actual construction costs. In testimony before the Senate committee in 1954, Fred admitted that he had built the Beach Haven apartment complex in Brooklyn for $3.7 million less than the amount of his government-insured loan. Although he was not charged with any crime, he was thereafter unable to obtain federal loan guarantees. A decade later a New York state investigation found that Fred had used his profit on a state-insured construction loan to build a shopping centre that was entirely his own property. He eventually returned $1.2 million to the state but was thereafter unable to obtain state loan guarantees for residential projects in the Coney Island area of Brooklyn.
Donald Trump attended New York Military Academy (1959–64), a private boarding school; Fordham University in the Bronx (1964–66); and the University of Pennsylvania’s Wharton School of Finance and Commerce (1966–68), where he graduated with a bachelor’s degree in economics. In 1968, during the Vietnam War, he secured a diagnosis of bone spurs, which qualified him for a medical exemption from the military draft (he had earlier received four draft deferments for education). Upon his graduation Trump began working full-time for his father’s business, helping to manage its holdings of rental housing, then estimated at between 10,000 and 22,000 units. In 1974 he became president of a conglomeration of Trump-owned corporations and partnerships, which he later named the Trump Organization.During the 1960s and early 1970s, Trump-owned housing developments in New York City, CincinnatiOhio, and NorfolkVirginia, were the target of several complaints of racial discrimination against African Americans and other minority groups. In 1973 Fred and Donald Trump, along with their company, were sued by the U.S. Department of Justice (DOJ) for allegedly violating the Fair Housing Act (1968) in the operation of 39 apartment buildings in New York City. The Trumps initially countersued the Justice Department for $100 million, alleging harm to their reputations. The suit was settled two years later under an agreement that did not require the Trumps to admit guilt.
In the late 1970s and the 1980s, Donald Trump greatly expanded his father’s business by investing in luxury hotels and residential properties and by shifting its geographic focus to Manhattan and later to Atlantic CityNew Jersey. In doing so, he relied heavily on loans, gifts, and other financial assistance from his father, as well as on his father’s political connections in New York City. In 1976 he purchased the decrepit Commodore Hotel near Grand Central Station under a complex profit-sharing agreement with the city that included a 40-year property tax abatement, the first such tax break granted to a commercial property in New York City. Relying on a construction loan guaranteed by his father and the Hyatt Corporation, which became a partner in the project, Trump refurbished the building and reopened it in 1980 as the 1,400-room Grand Hyatt Hotel. In 1983 he opened Trump Tower, an office, retail, and residential complex constructed in partnership with the Equitable Life Assurance Company. The 58-story building on 56th Street and Fifth Avenue eventually contained Trump’s Manhattan residence and the headquarters of the Trump Organization. Other Manhattan properties developed by Trump during the 1980s included the Trump Plaza residential cooperative (1984), the Trump Parc luxury condominium complex (1986), and the 19-story Plaza Hotel (1988), a historic landmark for which Trump paid more than $400 
million.

In the 1980s Trump invested heavily in the casino business in Atlantic City, where his properties eventually included Harrah’s at Trump Plaza (1984, later renamed Trump Plaza), Trump’s Castle Casino Resort (1985), and the Trump Taj Mahal (1990), then the largest casino in the world. During that period Trump also purchased the New Jersey Generals, a team in the short-lived U.S. Football League; Mar-a-Lago, a 118-room mansion in Palm Beach, Florida, built in the 1920s by the cereal heiress Marjorie Merriweather Post; a 282-foot yacht, then the world’s second largest, which he named the Trump Princess; and an East Coast air-shuttle service, which he called Trump Shuttle.
In 1977 Trump married Ivana Zelníčková Winklmayr, a Czech model, with whom he had three children—Donald, Jr., Ivanka, and Eric—before the couple divorced in 1992. Their married life, as well as Trump’s business affairs, were a staple of the tabloid press in New York City during the 1980s. Trump married the American actress Marla Maples after she gave birth to Trump’s fourth child, Tiffany, in 1993. Their marriage ended in divorce in 1999. In 2005 Trump married the Slovene model Melania Knauss, and their son, Barron, was born the following year. Melania Trump became only the second foreign-born first lady of the United States upon Trump’s inauguration as president in 2017.
When the U.S. economy fell into recession in 1990, many of Trump’s businesses suffered, and he soon had trouble making payments on his approximately $5 billion debt, some $900 million of which he had personally guaranteed. Under a restructuring agreement with several banks, Trump was forced to surrender his airline, which was taken over by US Airways in 1992; to sell the Trump Princess; to take out second or third mortgages on nearly all of his properties and to reduce his ownership stakes in them; and to commit himself to living on a personal budget of $450,000 a year. Despite those measures, the Trump Taj Mahal declared bankruptcy in 1991, and two other casinos owned by Trump, as well as his Plaza Hotel in New York City, went bankrupt in 1992. Following those setbacks, most major banks refused to do any further business with him. Estimates of Trump’s net worth during this period ranged from $1.7 billion to minus $900 million.
Trump’s fortunes rebounded with the stronger economy of the later 1990s and with the decision of the Frankfurt-based Deutsche Bank AG to establish a presence in the U.S. commercial real estate market. Deutsche Bank extended hundreds of millions of dollars in credit to Trump in the late 1990s and the 2000s for projects including Trump World Tower (2001) in New York and Trump International Hotel and Tower (2009) in Chicago. In the early 1990s Trump had floated a plan to his creditors to convert his Mar-a-Lago estate into a luxury housing development consisting of several smaller mansions, but local opposition led him instead to turn it into a private club, which was opened in 1995. In 1996 Trump partnered with the NBC television network to purchase the Miss Universe Organization, which produced the Miss Universe, Miss USA, and Miss Teen USA beauty pageants. Trump’s casino businesses continued to struggle, however: in 2004 his company Trump Hotels & Casino Resorts filed for bankruptcy after several of its properties accumulated unmanageable debt, and the same company, renamed Trump Entertainment Resorts, went bankrupt again in 2009.
In addition to his real-estate ventures, in 2004 Trump premiered a reality television series in which he starred, The Apprentice, which featured teams of contestants competing in various business-related projects, with a single contestant ultimately winning a lucrative one-year contract as a Trump employee (“apprentice”). The Emmy-nominated show, in which Trump “fired” one or more contestants on a weekly basis, helped him to further enhance his reputation as a shrewd businessman and self-made billionaire. In 2008 the show was revamped as The Celebrity Apprentice, with newsmakers and entertainers as contestants.
Trump marketed his name as a brand in numerous other business ventures including Trump Financial, a mortgage company, and the Trump Entrepreneur Initiative (formerly Trump University), an online education company focusing on real-estate investment and entrepreneurialism. The latter firm, which ceased operating in 2011, was the target of class-action lawsuits by former students and a separate action by the attorney general of New York state, alleging fraud. After initially denying the allegations, Trump settled the lawsuits for $25 million in November 2016. In 2019, more than two years into his presidency, Trump agreed to pay $2 million in damages and to admit guilt to settle another lawsuit by the attorney general of New York that had accused him of illegally using assets from his charity, the Trump Foundation, to fund his 2016 presidential campaign. As part of the settlement, the Trump Foundation was dissolved.
In 2018 The New York Times published a lengthy investigative report that documented how Fred Trump had regularly transferred vast sums of money, ultimately amounting to hundreds of millions of dollars, to his children by means of strategies that involved tax, securities, and real-estate fraud, as well as by legal means. According to the report, Donald was the main beneficiary of the transfers, having received the equivalent (in 2018 dollars) of $413 million by the early 2000s.
Trump was credited as coauthor of a number of books on entrepreneurship and his business career, including Trump: The Art of the Deal (1987), Trump: The Art of the Comeback (1997), Why We Want You to Be Rich (2006), Trump 101: The Way to Success (2006), and Trump Never Give Up: How I Turned My Biggest Challenges into Success (2008).
