Jerome Chodorov, 93, a playwright who co-wrote "My Sister Eileen," which he later adapted as the musical "Wonderful Town," died Sept. 12 at a hospital in Nyack, N.Y. No cause of death was reported.

"My Sister Eileen," which Mr. Chodorov wrote with Joseph A. Fields, was one of the playwright's biggest successes, opening on Broadway in 1940 and running for 865 performances. The story of two sisters from Ohio who come to conquer New York during the Depression starred Shirley Booth as the sardonic would-be writer Ruth Sherwood.

Rosalind Russell played the role in the 1953 musical version for which Mr. Chodorov and Fields supplied the book, Leonard Bernstein composed the music, and Betty Comden and Adolph Green wrote the lyrics. A revival is currently on Broadway with Donna Murphy portraying Ruth.

Mr. Chodorov had several other Broadway hits in the 1940s and early 1950s. He and Fields also wrote "Junior Miss," a warmhearted family comedy about a young girl who, after a series of misadventures, becomes a debutante. The 1941 show, based on Sally Benson's short stories, ran for 710 performances.

The team's third Broadway success was "Anniversary Waltz" (1954), starring Kitty Carlisle and Macdonald Carey. The comedy, which had a 615-performance run, received mostly negative notices, but audiences responded to its story of frantic marital discord and its satire of television, which was beginning to steal audiences away from Broadway.

In the early 1950s, Mr. Chodorov was blacklisted for a time after having been named in testimony before the House Committee on Un-American Activities as having attended meetings of the Communist Party.

Mr. Chodorov, who was born in New York, worked as a journalist for the New York World before moving to California, where he worked on more than 50 films, including "Louisiana Purchase" (1941) and "Those Endearing Young Charms" (1945), as well as film versions of both "My Sister Eileen" (1942) and "Junior Miss" (1945).

Among Mr. Chodorov's other plays with Fields were "The French Touch" (1946) and "The Ponder Heart" (1956), which they adapted from a Eudora Welty short story.

Mr. Chodorov also supplied the books for several other musicals, including "The Girl in Pink Tights" (1954), which was composer Sigmund Romberg's last Broadway musical, and "I Had a Ball" (1964), starring Buddy Hackett.

His last Broadway production was "A Talent for Murder," a comedy-mystery Mr. Chodorov wrote with Norman Panama and which starred Claudette Colbert and Jean-Pierre Aumont. It had a 10-week run in 1981.

His wife of 67 years, Rhea Chodorov, died in 1999.

Survivors include a daughter.
