Tom Lehrer, who died this weekend at 97, was surely the greatest satyrical song writer of the mid-20th Century. In the 1960s one had to be living in a hole under a rock in a cave not to have heard his works, which dispatched diverse sacred cows with equal enthusiasm. A brilliant mathematician, he exemplifed the goal of not taking oneself too seriously. The name Lehrer means "teacher" in German, fitting for any/all of his careers. His parting gift was to leave all his work to the public domain. Enjoy!
