The phrase "Founding Fathers" was first coined by U.S. Senator Warren G. Harding in his keynote speech at the Republican National Convention of 1916. Harding later repeated the phrase at his March 4, 1921, inauguration. While U.S. presidents used the terms "founders" and "fathers" in their speeches throughout much of the early 20th century, it was another 60 years before Harding's phrase would be used again during the inaugural ceremonies. Ronald Reagan referred to "Founding Fathers" at both his first inauguration on January 20, 1981, and his second on January 20, 1985.
