Robert Brown Thomson (October 25, 1923 – August 16, 2010) was a Scottish-born American professional baseball player. Nicknamed "The Staten Island Scot", he was an outfielder and right-handed batter for the New York Giants (1946–53, 1957), Milwaukee Braves (1954–57), Chicago Cubs (1958–59), Boston Red Sox (1960) and Baltimore Orioles (1960).
His pennant-winning three-run home run for the Giants in 1951, known as the "Shot Heard 'Round the World", is one of the most famous moments in baseball history. It overshadowed his other accomplishments, including eight 20-home run seasons and three All Star selections. "It was the best thing that ever happened to me", he later said. "It may have been the best thing that ever happened to anybody."
