Ronald Wilson Reagan (/ˈreɪɡən/; February 6, 1911 – June 5, 2004) was an American politician who served as the 40th president of the United States from 1981 to 1989 and became a highly influential voice of modern conservatism. At 69 years, 349 days of age at the time of his first inauguration, Reagan was the oldest person to assume the U.S. presidency, a distinction he held until 2017, when Donald Trump was inaugurated at age 70 years, 220 days. Reagan faced former vice president Walter Mondale when he ran for re-election in 1984 and defeated him, winning the most electoral votes of any U.S. president, 525, or 97.6% of the 538 votes in the Electoral College. After his wartime military service he co-starred in such films as The Voice of the Turtle, John Loves Mary, The Hasty Heart, Bedtime for Bonzo, Cattle Queen of Montana, Tennessee's Partner, Hellcats of the Navy (the only film in which he appears with Nancy Reagan), and the 1964 remake The Killers (his final film).
