The latest production from St. Louis Actors’ Studio is a collaboration with a company I had heard of, but hadn’t seen because they had disbanded before I started reviewing theatre in St. Louis. The Orange Girls’ semi-reunion is well-chosen, considering the focus of the latest production of the achievements, challenges, and deep friendship of the women featured in Lauren Gunderson’s well-structured The Half-Life of Marie Curie. Thoughtfully directed by Nancy Bell and featuring some truly stunning production designs, this show highlights a terrific cast and two important figures in the history of women in science.
The story, set mostly in 1912, focuses on renowned, widowed Polish-French scientist Marie Curie (Meghan Baker), who is in the midst of a scandal involving her affair with a married French scientist. Hounded by the press, Curie is soon visited by her close friend, British engineer and mathematician Hertha Ayrton (Michelle Hand), who invites Curie to join her at her remote seaside cottage in England to avoid the press attention. Curie eventually agrees to go, bringing with her a glowing vial of radium–the element she discovered–that she keeps in her pocket. During her stay at Ayrton’s cottage, the two women engage in discussions and debates involving women’s suffrage–a passionate cause on Ayrton’s part–their relationships with their late husbands, the treatment of women in science, double standards involving men and women in affairs, and more. It’s a fascinating look at a close female friendship as well as the struggles of women to be seen as equals in the scientific field, and in society in general, as well as the wonders and dangers of new scientific discoveries, and the fragile nature of life itself, represented by the recurrent ticking of a clock.
The production is well-measured and remarkably well cast, featuring two of the three Orange Girls founders, Baker and Hand, at their best. Baker’s Curie is at once thoughtful, reticent, and determined, while Hand’s Ayrton is fiery and assertive while also being intensely loyal and encouraging. The two make a great team, bringing much relatability and warmth to their bonding moments, especially in a both hilarious and profound sequence in which the two share a bottle of whisky. The historical and biographical elements of the story are woven expertly into the relationship moments, making for a realistic and engaging portrait of a deep friendship as well as a snapshot of a moment in history.
In addition to the fantastic cast and pacing, the production design is simply fantastic, with a striking “picture frame” style set by Patrick Huber that highlights a beautiful backdrop painting by Andy Cross as an homage to German painter Anselm Kiefer’s Für Gregory Corso. Denisse Chavez’s lighting is also remarkable, highlighting the set and the shifting moods and tensions of the story, and Kristi Gunther’s sound provides that recurring tick, the hiss of arc lights, and more in lending an air of authenticity to the proceedings. There’s also wonderfully detailed work from Teresa Doggett on the stylish and period-appropriate costumes, and from Maria I. Straub-David on props design. It’s an expertly designed production that brings the audience into the characters’ world and times, as well as into their minds and feelings with vivid intensity.
The Half-Life of Marie Curie is a profoundly fascinating production. Featuring a welcome reunion of a celebrated St. Louis theatre company and highlighting the works and relationships of brilliant and determined women, it’s a show that educates while it entertains. It’s also a master-class in acting from its two leads. It’s a must-see production from STLAS and the Orange Girls.
The Orange Girls and St. Louis Actors’ Studio are presenting The Half-Life of Marie Curie at the Gaslight Theater until April 19, 2026
