As a cardiologist and United Airlines captain, William Hamman taught doctors and pilots ways to keep hearts and planes from crashing. He shared millions in grants, had university and hospital posts, and bragged of work for prestigious medical groups. But it turns out Hamman isn?t a cardiologist or even a doctor. The AP found he had no medical residency, fellowship, doctoral degree or the 15 years of clinical experience he claimed. David Nacht, an employment lawyer in Ann Arbor, Mich., acknowledged that his client did not have the medical and doctoral degrees he had claimed from the University of Wisconsin-Madison in the 1980s.
