Frederick Christ Trump (October 11, 1905 – June 25, 1999) was an American real estate developer, primarily in New York City, and father of Donald Trump, the 45th president of the United States, and Maryanne Trump Barry, a United States Court of Appeals judge.
Fred Trump's father Frederick died when Fred was 12 years old. By 15, in partnership with his mother Elizabeth Christ Trump and non-family investors, Trump had begun 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. 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.
