Lewis F. Powell Jr. came to the U.S. Supreme Court in 1972 reluctantly and at an age when many professionals are anticipating retirement rather than a career change. But the Court suited him. He grew to love the work, although he often found it agonizing, and he thrived on the role he played in the history of the Constitution.
