On January 30, 1948, at the age of 53, Herb Pennock collapsed in the lobby of the Waldorf-Astoria Hotel in New York City as a result of a cerebral hemorrhage. He was pronounced dead upon his arrival at Midtown Hospital. Pennock had played from 1912 through 1933, and was best known for his time spent with the New York Yankee teams of the mid- to late-1920s and early 1930s. After retiring as a player, Pennock served as a coach and farm system director for the Red Sox, and as general manager of the Philadelphia Phillies. Later in 1948, he was posthumously inducted into the National Baseball Hall of Fame.
