Frederick Christ Trump (October 11, 1905 – June 25, 1999) was an American real estate developer in New York City and the father of Donald Trump, the 45th president of the United States, and Maryanne Trump Barry, a former United States Court of Appeals judge.
In partnership with his mother Elizabeth Christ Trump, he began a career in home construction and sales. The development company was incorporated as Elizabeth Trump & Son in 1927, and grew to build and manage single-family houses in Queens, barracks and garden apartments for U.S. Navy personnel near major shipyards along the East Coast, and more than 27,000 apartments in New York City.
Trump was investigated by a U.S. Senate committee for profiteering in 1954, and again by the State of New York in 1966. He made Donald the president of Trump Management Company in 1971, and they were sued by the U.S. Justice Department's Civil Rights Division for violating the Fair Housing Act in 1973. Throughout his career he contributed to local hospitals, various American nonprofit organizations, and international Jewish causes.
