Madover, whose Broadway producing credits include Annie, Hair, Lucky Guy, Frost/Nixon and I'll Eat You Last: A Chat With Sue Mengers, joined the Public's board in 2009 and has served as board vice-chair for the past year. She begins a three-year term immediately.
Madover succeeds Warren Spector, who has been the Public Theater's board chair since 2005. He will remain on the organization's executive committee.
"As a New York City native, I was so fortunate to experience first-hand the work and influence of The Public Theater," Madover said in a statement. "Not only is The Public an essential part of life in New York, it has served as a role model and leader for cultural institutions in the U.S. and indeed the world. I am very excited to work with the rest of the Board, Oskar Eustis, Patrick Willingham, and the staff of The Public Theater as they continue to remain true to the theatre's ongoing mission of making theatre accessible to all."
