Betty Comden (May 3, 1917 – November 23, 2006) was one-half of the musical-comedy duo Comden and Green, who provided lyrics, libretti, and screenplays to some of the most beloved and successful Hollywood musicals and Broadway shows of the mid-20th century. Her writing partnership with Adolph Green, called "the longest running creative partnership in theatre history",lasted for six decades, during which time they collaborated with other leading entertainment figures such as the famed "Freed Unit" at MGM, Jule Styne and Leonard Bernstein, and wrote the musical comedy film Singin' in the Rain. 　　Betty Comden was born Basya Cohen in Brooklyn, New York, to Leo (Sadvoransky) Cohen, a lawyer, and her mother, Rebecca, an English teacher, were both Russian immigrants, both observant Jews. Basya "attended Erasmus Hall High School and studied drama at New York University, graduating in 1938." according to the New York Times. 　　In 1938, mutual friends introduced her to Adolph Green, an aspiring actor. Along with the young Judy Holliday and Leonard Bernstein, Comden and Green formed a troupe called the Revuers, which performed at the Village Vanguard, a club in Greenwich Village. Due to the act's success, the Revuers appeared in the 1944 film Greenwich Village, but their roles were so small they were barely noticed, and they returned to New York. 　　Comden and Green's first Broadway show was in 1944, with On the Town, a musical about three sailors on leave in New York City that was an expansion of a ballet entitled Fancy Free on which Bernstein had been working with choreographer Jerome Robbins. Comden and Green wrote the book and lyrics, which included sizable parts for themselves (as "Claire" and "Ozzie"). Their next musical, Billion Dollar Baby in 1945, with music by Morton Gould was not a success, and their 1947 show Bonanza Bound closed out-of-town and never reached Broadway.
