Justice John Paul Stevens loved to tell the story of seeing, as a boy of 12, Babe Ruth’s famous “called shot” home run in the 1932 World Series game between his beloved Chicago Cubs and the New York Yankees. Watching Stevens perform his duties as a Supreme Court justice was a comparable experience — seeing one of the greats perform at the height of his abilities, exceeding expectations in every situation, no matter how historic or pressured. If there is a Supreme Court hall of fame, he surely has a prominent place.
