Tom Lehrer, the Harvard-trained mathematician whose wickedly iconoclastic songs made him a favorite satirist in the 1950s and ’60s on college campuses and in all the Greenwich Villages of the country, died on Saturday at his home in Cambridge, Mass. He was 97.

His death was confirmed by David Herder, a friend.

Mr. Lehrer’s lyrics were nimble, sometimes salacious and almost always sardonic, sung to music that tended to be maddeningly cheerful. Accompanying himself on piano, he performed in nightclubs, in concert and on records that his admirers purchased, originally by mail order only, in the hundreds of thousands.

But his entertainment career ultimately took a back seat to academia. In his heart he never quit his day job; he just took a few sabbaticals.
