Bill Cosby is one of the most influential performers of the last half century. From a poor Philadelphia neighborhood, he rose to dominate the airwaves through shows like I Spy and The Cosby Show; become the all-time bestselling comedian on records; and author several blockbuster books, including Fatherhood, which became the fastest-selling hardcover book of all time and spent 54 weeks on the New York Times bestseller list. A crusader throughout his career, his success is complemented by involvement with a host of charitable, education, and civil rights organizations.
