To celebrate the Eugene O'Neill Theater Center's 50th anniversary and influence, The New York Public Library for the Performing Arts at Lincoln Center will present “Launchpad of the American Theater: The O'Neill Since 1964,” a new free multimedia exhibition on display in the Vincent Astor Gallery (111 Amsterdam Ave) May 17 through Sept 16. The exhibition will chart the journey of American theater at the O'Neill from its past to present and future, and explore the creative development of its playwrights, composers, students, puppeteers and performers.
