He was active freemason of masonic lodge Josef Dobrovský in Plzeň.[2]
During the Nazi occupation of Czechoslovakia, Skupa performed satiric and allegorical puppet plays on hundreds of stages all over Czechoslovakia. After 1945, he moved his theatre to Prague. He was praised as an official "national artist" during the Communist regime but he was criticised for his lack of political engagement. Therefore, Skupa focused on plays for children, and mime with puppets for adults. He also performed abroad (Great Britain, Poland, France, Hungary, USSR).[1]
His wife was a puppeteer Jiřina Skupová (born Schwarzová). [3]
