Frederick Lieb (March 5, 1888 – June 3, 1980) was an American sportswriter and baseball historian. He and his wife Mary were especially close to Lou Gehrig. Walter Brennan's character in the movie The Pride of the Yankees was loosely based on him. He was also known for coming up with the nickname for Yankee Stadium - 'The House that Ruth Built.'
In 1977, when he was 89 years old, Lieb published his memoirs, which documented his nearly 70 years as a baseball reporter.
Born in Philadelphia, Pennsylvania, Lieb died at age 92 in Houston, Texas.
