In the early-1960s Viola Spolin took on an assistant and protégé, Josephine Forsberg, to help with her workshops at the Second City, as well as with her children's theatre that performed there on weekends. Viola Spolin eventually handed both the children's show and the improv classes over to Forsberg, who continued teaching Spolin's work at the Second City from the mid-1960s on, leading to the creation of Forsberg's own improv school, Players Workshop in 1971, as well as the Improv Olympic and the Second City Training Center in the 1980s, all of which were based on Spolin's work.
