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.
