The Cort Theatre is named after John Cort, founder of the Northwestern Theatrical Association. He commissioned Thomas W. Lamb to design the theatre which would mirror the Petit Trianon in Versailles. It officially opened on 20th December 1912 with Peg o' My Heart starring Laurette Taylor. The Shuberts acquired the theatre in 1927, two years before Cort’s death. It has always been used as a traditional theatre except for the years from 1969 to 1972 when it became a television studio with the broadcast of "The Merv Griffin Show".
In March 2021, renovation works will begin at the Cort Theatre. The new annex will include dressing rooms, rehearsal spaces and larger wings. The Cort Theatre is currently set to reopen in 2022 with The Minutes.
