Thomson, (Robert Brown) Bobby(1923– ) baseball player; born in Glasgow, Scotland. He came to the U.S.A. at age two. He participated in one of baseball's most memorable moments in 1951 when he hit a home run—called "the shot heard around the world"—in the ninth inning of a deciding play-off game against the Brooklyn Dodgers to win the National League pennant for the New York Giants. A fine outfielder, he hit 20 or more home runs eight times during his 15-year career (1946–60).
