Theodore Roosevelt "Double Duty" Radcliffe (July 7, 1902 – August 11, 2005) was a professional baseball player in the Negro leagues. An accomplished two-way player, he played as a pitcher and a catcher, became a manager, and in his old age became a popular ambassador for the game. He is one of only a handful of professional baseball players who lived past their 100th birthdays, next to Red Hoff (who lived to 107) and fellow Negro leaguer Silas Simmons (who lived to age 103).
