How it started
History
The International Theatre was one of the two professional English-language theatres in Vienna (the other being Vienna's English Theatre). It was founded in 1974 by American opera-singers William and Marilyn Wallace and started as a touring company. The first performance (Blithe Spirit, by Noël Coward) premiered in Graz in November 1974. For the next few years the Wallaces toured shows like Samuel Beckett's Happy Days around the provinces. The IT found its first permanent home in Vienna's 9th district, at the disused Rossauer Cinema on Glasergasse. After several years there, it moved to its present home on January 14, 1980. After the death of her husband William in 2001, Marilyn Wallace assumed the role of executive producer.
