Sid Kuller (27 October 1910 New York City, New York – 16 September 1993 in Sherman Oaks, California) was an American comedy writer, producer and lyricist/composer, who concentrated on special musical material, gags and sketches for leading comics. He collaborated with Ray Golden and Hal Fimberg on the screenplay of the Marx Brothers' vehicle The Big Store, for which he also supplied the lyrics to the musical climax, "The Tenement Symphony". Earlier in their careers, Kuller and Golden wrote comedy songs and special material for the Ritz Brothers. Although he wrote prodigiously and with facility throughout his life, Kuller admitted, "The creation of comedy is a painful experience".
After attending Columbia University, Kuller began contributing jokes and songs to vaudeville performers, such as Bert Lahr and Jack Benny, and became a ghost-gag-writer for the legendary Al Boasberg. While working on an Earl Carroll Vanities show he started to write comedy bits for the precision-dancing Ritz Brothers, who brought him and fellow-writer Ray Golden with them to Hollywood in 1937.
On Broadway Kuller and Golden were part of the team which wrote the book for the progressive 1940 revue Meet the People, which included one of his early hit songs Elmer's Wedding Day (with music by Jay Gorney). He also wrote the political musical revue, O Say Can You Sing, which was performed in Chicago, and may have been one of the producers of the original Chicago production of the Federal Theater Project's groundbreaking all-black Swing Mikado., which transferred to Broadway without him.
