The theater opened in the fall of 1939 and was designed by architect Michael Hare. Statewide radio broadcast the October 8th inaugural ceremonies, and the next three days saw four performances of Shakespeare's The Taming of the Shrew, starring the leading couple of the American theater, Alfred Lunt and Lynn Fontanne. Union Theater audiences have seen and heard some of the most famous public figures, actors, dancers and musicians in performances over the last 70 years. Eleanor Roosevelt, Fritz Kreisler, Ella Fitzgerald, Indian Prime Minister Nehru, Frank Lloyd Wright, Yo-Yo Ma, T. S. Eliot, Jesse Jackson, Arthur Rubinstein, Jascha Heifetz, Martin Luther King, Jr., Robert Frost, Itzhak Perlman, John F. Kennedy, Louis Armstrong, Martha Graham, Ted Turner, Kurt Vonnegut and Dave Brubeck have all appeared at the Wisconsin Union Theater. The Wisconsin Union Directorate allows students to participate in the programming and execution of performances at the theater. Every year, students work with the Union Theater staff on artist booking, contracts, box office and front-of-the-house management, backstage and technical crews, production, business operations, and publicity. In 2006, a student referendum was held for the third time on funding the remodeling of Union South and the Memorial Union. The referendum passed. The Arts and Recreation Wing of Memorial Union is undergoing remodeling work in 2012-2014.. Renovations were completed in June 2014, which marked the 75th anniversary for the Wisconsin Union Theater. Renovations included Shannon Hall - the largest space in the Union Theater with 1135 seats, The Play Circle - a technological space with room for 300, and finally the Festival Room - a new performance space for classes and workshops.
Controversy over KKK affiliation
The Play Circle, formerly named after Fredric March, was renamed in 2018 after research commissioned by Chancellor Rebecca Blank outlined March's association with the white nationalist supremacist group, the Ku Klux Klan. On the publication of that research and an article in the Capital Times about the history of the KKK at the University, students submitted a hate and bias report in response to the names. This pressure forced the Union to take down and cover up the names of both The Play Circle and an adjacent art gallery, named after Porter Butts. A published statement suggested they would form a "social justice incubator" to address systems of white supremacy at the university.
