Donald John Trump (born June 14, 1946) is the 45th and current President of the United States, in office since January 20, 2017. Before entering politics, he was a businessman and television personality. Trump was born and raised in the New York City borough of Queens, and earned an economics degree from the Wharton School of the University of Pennsylvania. He took over his family's real estate business in 1971, renamed it The Trump Organization, and expanded it to involve the construction and renovation of skyscrapers, hotels, casinos, and golf courses.
Ancestry and parents
Trump's ancestors originated from the German village of Kallstadt in the Palatinate on his father's side, and from the Outer Hebrides in Scotland on his mother's side. All of his grandparents and his mother were born in Europe.  Trump's paternal grandfather, Friedrich Trump, first emigrated to the United States in 1885 at the age of 16 and became a citizen in 1892. He amassed a fortune operating boom-town restaurants and boarding houses in the Seattle area and the Klondike region of Canada during its gold rush. On a visit to Kallstadt, he met Elisabeth Christ and married her in 1902. The couple permanently settled in New York in 1905. Frederick died from influenza during the 1918 pandemic.  Trump's father Fred was born in 1905 in The Bronx. Fred started working with his mother in real estate when he was 15, shortly after his father's death. Their company, Elizabeth Trump & Son, was primarily active in the New York boroughs of Queens and Brooklyn. Fred eventually built and sold thousands of houses, barracks, and apartments. The company was later renamed The Trump Organization, after Donald Trump took charge in 1971.  Trump's mother Mary Anne was born in Tong, Lewis, Scotland. At age 18 in 1930, she emigrated to New York, where she worked as a maid. Fred and Mary were married in 1936 and raised their family in Queens.  Trump's uncle John was an electrical engineer, physicist, and inventor. He worked as a professor at MIT from 1936 to 1973. During World War II, he was involved in radar research for the Allies and helped design X-ray machines that were used to treat cancer.
