Wasserman, according to the Seattle Times article, later recovered the full rights to his "Cuckoo's Nest" script, and the play has been produced in regional theaters and abroad. In 2001, it won a Tony Award for best revival of a play.
Wasserman was born Nov. 2, 1914, in Rhinelander, Wis. Orphaned at age 9, he lived in a state orphanage and briefly with an older brother in South Dakota before hitting the rails.
"I'm a self-educated hobo," Wasserman told the Daily Breeze in 2001. "My entire adolescence was spent as a hobo, riding the rails and alternately living on top of buildings on Spring Street in downtown Los Angeles.
"The only education I got was by reading. . . . I regret never having received a formal education. But I did get a real education about human nature, though that was a tough one at times."
While living on a Spring Street rooftop at 19, he told The Times in 1995, he joined a street-theater troupe called the Rebel Players.
Among other things, he worked as a stage manager, was a director for the Federal Theatre Project and did stage and lighting design for Katherine Dunham's dance company.
He also was an original producer of the 1946 Broadway musical "Beggar's Holiday," Duke Ellington's jazz version of John Gay's "The Beggar's Opera." The production drew pickets for featuring an interracial romance.
Six decades later, Wasserman restructured the script and rewrote the book and lyrics for a new production of the musical that had its world premiere with the Marin Theater Company in 2004.
Before his death, Wasserman was working on several new plays and looking forward to the Jan. 9 opening of his new comedy "Premiere!" at Theater Works in Peoria, Ariz.
He is survived by his wife of 30 years, Martha.
At Wasserman's request, there will be no service.
