The New York Yankees were the strongest team in the major leagues from 1948-1960, capturing the American League Pennant 10 times and winning seven World Championships. Ask the average baseball fan who made the Yankees so dominant and most will mention players such as Joe DiMaggio, Yogi Berra, Whitey Ford, or Mickey Mantle. Some may insist that manager Casey Stengel was the key. But sports pundits at the time, and respected sports historians today consider the real genius behind the Yankees' success their general manager, a portly, often taciturn, and very shy man named George Martin Weiss. Weiss loved baseball but lacked the ability to play the game. What he had was the savvy to run a baseball team better than virtually anyone he competed against. Weiss spent more than 50 years in baseball, including nearly 30 years with the Yankees. Before he was Yankee GM, he created and ran their superlative farm system that continuously supplied talented players to the parent club. When the Yankees fired him at age 67, because he was ""too old"", the newly franchised New York Mets immediately hired him to build their team. This is the first in-depth biography of George M. Weiss, who, when inducted into Baseball's Hall of Fame in 1972, was hailed for contributing ""as much to baseball as any man the game could ever know.
