Billionaire-turned-mayor Michael Bloomberg challenged the beliefs that businessmen make inept politicians and that charisma is a prerequisite for the job of mayor. Joyce Purnick’s new biography, Mike Bloomberg: Money, Power, Politics, illuminates the man behind the public persona.

On Tuesday, September 29, from 8:30 to 10:00 a.m., Glenn Thrush, senior congressional reporter for Politico.com, moderates a discussion with participants including Joyce Purnick and Doug Muzzio, professor at Baruch College School of Public Affairs. The discussion, held in conjunction with the Center for New York City Affairs, centers on how Bloomberg and his money have reshaped the mayoralty, remade city politics, and upended notions of independent urban leadership.

This event, supported by the Sirus Fund and the Milano Foundation, will be held in the Theresa Lang Community and Student Center, Arnhold Hall, 55 West 13th Street, 2nd floor. It is free, but seating is limited and reservations are required. Reserve a place by calling 212.229.5418 or emailing centernyc@newschool.edu.

Following the discussion, Joyce Purnick will be on hand to sign copies of her new book, which will be available for purchase.
