Having just turned 90, Weil, Gotshal & Manges senior partner Ira Millstein still has an active practice advising nonprofits, including New York’s Central Park Conservancy, while continuing his decades-long fight to reform corporate boards.

During Millstein’s long and influential career at Weil, he counseled clients such as General Electric Co., General Motors Co., the Planned Parenthood Federation of America Inc. and New York City’s mayor during its 1970s fiscal crisis. (Millstein prepared the papers for an aborted municipal bankruptcy filing by the Big Apple.)
