Frederick Christ Trump (middle name pronounced ; October 11, 1905 – June 25, 1999) was an American real estate developer and businessman. He was the father of Donald Trump, the 45th and 47th president of the United States, along with four other children.

Born in the Bronx in New York City to German immigrant parents, Trump began working in home construction and sales in the 1920s before heading the real-estate business started by his parents (later known as the Trump Organization). From World War II onward, to avoid associations with Nazism, Trump denied his German ancestry and also supported Jewish causes.

Decades after hiring PR man Howard Rubenstein to generate press about his life story mirroring the rags-to-riches novels of 19th-century author Horatio Alger, in 1985, Fred was awarded the Horatio Alger Award (for "distinguished Americans"). Radio and television personality Art Linkletter introduced Trump at the ceremony, with Protestant minister Norman Vincent Peale's wife (and previous award recipient), Ruth Peale, presenting him the award. During his speech, Trump stated that the key to his success was enthusiasm for his work and that he "used to watch other successful people ... that did good and that did bad and ... followed the good qualities that they had". He then (apparently erroneously) attributed to William Shakespeare the saying "Never follow an empty wagon because", pointing to his cranium, "nothing ever falls off". He went on to introduce his surviving family. In addition to money, Trump may have worked with Tomasello to avoid problems with the mafia or unions. From 1959 to 1961, Tomasello sued Trump in the New York Supreme Court as a stockholder of 25% of ten of Trump's corporations, as well as 14 subsidiaries and 4 sub-subsidiaries. were cited as examples of how profits were made by builders using the FHA. The two paid $34,200 for a piece of land which they rented to their corporation for $76,960 annually in a 99-year lease, so that if the apartment they built on it ever defaulted, the FHA would owe them $1.924 million. Trump and Tomasello evidently obtained loans for $3.5 million more than Beach Haven Apartments had cost. The project was constructed in 1963–64 for $70 million. It was one of Trump's biggest and last major projects, and the only one to bear his name. The next year, he announced plans for a enclosed dome with recreational facilities and a convention center. At a highly publicized ceremony in September 1966, Trump demolished the park's Pavilion of Fun, a large glass-enclosed amusement center. He reportedly sold bricks to ceremony guests to smash the remaining glass panels, which included an iconic representation of the park's mascot, the "Funny Face". The next month, New York City announced plans to acquire the former park grounds for recreational use. Trump filed a series of court cases related to the proposed rezoning, ultimately winning $1.3 million.

In July 2016, the Coney Island History Project held a special exhibit for the "50th Anniversary of Fred Trump's Demolition of Steeplechase Pavilion".

Fred's son Donald joined his father's real-estate business around 1968, initially working in Brooklyn. That year, Fred reputedly secured Donald a deferment from the Vietnam War by prioritizing maintenance for a tenant who (ostensibly in exchange) diagnosed Donald with bone spurs. In 1971, Donald became president of the company, with Fred becoming chairman. The younger Trump entered the real-estate business in Manhattan, while his father operated primarily in Brooklyn, Queens, and Staten Island.

According to some sources, Fred himself planned the expansion to Manhattan. His granddaughter Mary L. Trump states that he was "intimately involved in all aspects of Donald's early forays into the Manhattan market". Louise Sunshine (organization vice president from 1973 to 1985) claims Fred was "behind [Donald] in every way, shape and form [including] financing". According to another source, Fred came to work "every day until ... he went to the hospital".

In the mid-1970s, Donald received loans from his father exceeding $14 million. In 2015–16, during his campaign for U.S. president, Donald claimed that his father had given him "a&nbsp;small loan of a million dollars" which he used to build "a company that's worth more than $10 billion". An October 2018 New York Times exposé on Fred and Donald Trump's finances revealed that Fred created 295 income streams for Donald and concludes that the latter "was a millionaire by age&nbsp;8", receiving $413 million (adjusted for inflation; $483.6 million in 2023 currency) from Fred's business empire over his lifetime, including over $60.7 million (unadjusted for inflation; <!--$140m as of 2018-->$163.9 million in 2023 currency) in loans, which were largely unreimbursed.

According to Trump construction vice president Barbara Res, Fred seated business guests in an off-balance chair and advised Donald to arrange his office so that adversaries could be forced to face the sun.

Federal civil rights lawsuit

Minority applicants turned away from renting apartments complained to the New York City Commission on Human Rights and the Urban League, leading these groups to send test applicants to Trump-owned complexes in July 1972. They found that white people were offered apartments, while black people were generally turned away (by being told there were no vacancies);
