Ellsworth Tenney "Babe" Dahlgren (June 15, 1912 – September 4, 1996) was an American professional baseball infielder. He played twelve seasons in Major League Baseball from 1935 to 1946 for the Boston Red Sox, New York Yankees, Boston Braves, Chicago Cubs, St. Louis Browns, Brooklyn Dodgers, Philadelphia Phillies, and Pittsburgh Pirates. Dahlgren is perhaps best remembered for replacing Lou Gehrig in the lineup on May 2, 1939, which ended Gehrig's 14-year, 2,130 consecutive game streak. Dahlgren hit a home run and a double as the Yankees routed Detroit 22–2. He went on to hit 15 home runs and drive in 89 runs for the season for the Yankees.
