Happy Medium Theatre

The Happy Medium Theatre, also known as The Happy Medium and the Happy Medium Discotheque, was a theatre and nightclub located in Chicago, Illinois at 901 N. Rush St. 60611. Founded by George and Oscar Marienthal, it opened as a jazz nightclub in 1959 and became a legitimate theatre in 1960. It principally operated as a venue for small scale musicals of the cabaret variety and less frequently plays until 1974 when Paul G. Magit reimagined it as a concert venue. In its later years it operated as two distinct venues under a single organization. Its lower floor was used as a performance space for primarily jazz musicians in connection with Joe Segal's Jazz Showcase, and its upper floor was a disco nightclub. It closed in the early 1980s; sometime after October 1981.
