In April, 1952, I traveled to Lambarene, then in French Equatorial Africa, to try to enlist the leadership of Albert Schweitzer for the cause of world peace. I was disappointed to find him basically unconcerned about world politics, skeptical of the United Nations, indifferent to disarmament, and unwilling even to lend his name to peace efforts. A decade later, in June, 1962, I saw Schweitzer for the last time. He was then a world leader in nuclear disarmament, and my task this time, also unsuccessful, was to discourage his indiscriminate endorsements of some peace efforts which I believed misguided.
