Marketa Kimbrell, a Czechoslovak-born actress, director, and theater teacher, was a prominent figure in American political theater. Trained at the Actors Studio under the guidance of Lee Strasberg, she began her career with appearances in films such as *Dog Day Afternoon* (1975). The cornerstone of her work was the founding of the New York Street Theatre Caravan in 1970, a traveling theater company dedicated to non-traditional audiences. Through performances with strong social and political engagement, often inspired by Brechtian techniques, the Caravan brought theater to prisons, Native American reservations, migrant worker camps, and disadvantaged communities. For her pioneering work and consistent artistic quality with the company, Kimbrell received a prestigious Obie Award for Sustained Excellence in 1982, solidifying her role as an innovator in engaged theater. Her career was entirely dedicated to making the art of theater a tool for social change and for dialogue with marginalized communities.
