The Effect of Gamma Rays on Man-In-The-Moon Marigolds

Winner of the 1971 Pulitzer Prize for Drama

Run Dates: March 20-30

Director: Emma Denny

Tickets: $25 in advance or $30 at the door. Group rates are available for parties of 10+.


This powerful and moving study of an embittered, vindictive widow and her two young daughters has been hailed as one of the most significant and affecting plays of our time.

Supporting herself and her two daughters by taking in a decrepit old boarder, acid-tongued Beatrice Hunsdorfer wreaks a petty vengeance on everyone around her. Her older daughter, Ruth, is a pretty but highly strung girl subject to convulsions, while her younger girl, Tillie, plain and almost pathologically shy, demonstrates an intuitive gift for science. 

Encouraged by her teacher, Tillie conducts a botanical experiment, winning a prize at her high school. Proud but jealous, too filled with her own hurt to accept her daughter's success, Beatrice can only maim when she needs to love and deride when she intends to praise. Yet, as Tillie's experiment proves, something beautiful and full of promise can emerge from even the most barren, afflicted soil.
