Mark H. McCormack (1930-2003) grew up in Chicago, graduated from William & Mary College and Yale Law School and moved to Cleveland, Ohio, to begin his legal career. While practicing law in Cleveland, he began International Management Group on a handshake with Arnold Palmer in 1960, launching the modern-day sports marketing industry. IMG continues to be the most dominant agency in global sports today.
After publication of What They Don't Teach You at Harvard Business School in 1984, McCormack also became a bestselling author of business advice books, focusing on practical, street-smart counsel to help entrepreneurs succeed in any business environment. Through a gift from the McCormack family foundation, Mark McCormack's files and papers were donated to the Special Collections department at the UMass Amherst Libraries in Amherst, Massachusetts.
