Sidney Joseph Perelman, almost always known as S. J. Perelman (February 1, 1904 – October 17, 1979), was a Jewish-American humorist, author, and screenwriter. He is best known for his humorous short pieces written over many years for The New Yorker. He also wrote for several other magazines, as well as books, scripts, and screenplays.
In cinema, Perelman is noted for co-writing scripts for the Marx Brothers films Horse Feathers and Monkey Business and for the Academy Award-winning screenplay Around the World in Eighty Days.
With Ogden Nash he wrote the book for the musical One Touch of Venus (music by Kurt Weill, lyrics by Nash), which opened on Broadway in 1943 and ran for more than 500 performances. His play The Beauty Part (1962), which starred Bert Lahr in multiple roles, fared less well, its short run attributed at least in part to the accompanying 114-day 1962 New York City newspaper strike.
