Michael Bloomberg is not only New York City's 108th mayor; he is a business genius and self-made billionaire. He has run the toughest city in America with an independence and show of ego that first brought him great success—and eventually threatened it. Yet while Bloomberg is internationally known and admired, few people know the man behind the carefully crafted public persona. In Mike Bloomberg, Joyce Purnick explores Mr. Bloomberg's life from his childhood in the suburbs of Boston, to his rise on Wall Street and the creation of Bloomberg L.P., to his mayoral record and controversial gamble on a third term. Drawing on her deep knowledge of New York City politics, and interviews with Bloomberg's friends, family, colleagues, and the mayor himself, she creates a textured portrait of one of the more complex men of our era.
