Jon Pessah is the author of "Yogi: A Life Behind the Mask" a biography of Yogi Berra, the New York Yankees icon, winner of 10 World Series championships, and the most-quoted player in baseball history.Overshadowed on the field by Joe DiMaggio early in his career and later by a youthful Mickey Mantle, Berra emerges as not only the best loved Yankee but one of the most appealingly simple, innately complex, and universally admired men in all of America.
