Michael Joseph Sheehy
Big Pete Sheehy was a thread through Yankee history. When Lou Gehrig realized his career was over, he flipped his glove to Sheehy, who said "I'm done, Pete." Sheehy was the man who issued Mickey Mantle #7 after Mantle was recalled from Kansas City so he could get a new start rather than being pressed with number 6.
Sheehy was the equipment manager for the New York Yankees from age 17 until his death at age 75. He witnessed home runs by Babe Ruth and the MVP season of Don Mattingly. Between, he was part of the organization for 21 World Series titles and eight additional American League pennants.
Sheehy died suddenly in August 1985, still employed by the club. The home clubhouse at Yankee Stadium is named for him. There is also a plaque in the dugout that reads "Pete Sheehy, 1927-85, Keeper of the Pinstripes."
