First Folio Theatre is a not-for-profit theater company affiliated with the Actors' Equity Association. Founded in 1996, First Folio, originally named First Folio Shakespeare Festival, is located on the grounds of the Mayslake Peabody Estate in Oak Brook, Illinois, United States. First Folio utilizes the "Folio Method" as developed by Patrick Tucker (at one time of the Royal Shakespeare Company), who first introduced his approach to American actors, directors and teachers in a series of workshops sponsored by the Riverside Shakespeare Company of New York City at The Shakespeare Center beginning in 1982, which led to an awakened interest in the First Folio.
