Born in Chicago in 1928, Mrs. Sher teamed with her husband Louis K. Sher on a few shows, beginning with the Civil War-set antiwar musical Shenandoah, which starred John Cullum in a Tony-winning performance. Bowing in 1975, it ran for two-and-a-half years on Broadway and was nominated for a Tony Award. It was the Sher's biggest success. On that show, the Shers co-produced with Philip Rose. The trio again worked together, though with less success, on The Trip Back Down, a play by John Bishop that starred Cullum. The Shers also produced the 1978, backward-looking dance revue The American Dance Machine, which lasted nearly 200 performances.
On her own, Mrs. Sher produced Tennessee Williams' short-lived Eccentricities of a Nightingale in 1976. With Inacent Black in 1981, her Broadway producing career was over.
Mrs. Sher is survived by her husband Frederick Evans, her daughter Bonnie Hope Sher, grandson Daniel Louis Ratner and great-grandchildren Aaron and Elizabeth Ratner.
