Paul Cushman is a retired internal medicine physician. A graduate of Yale University (1951) and Columbia College of Physicians and Surgeons (1955), he devoted his medical talents to the field of endocrinology as well as the clinical, pharmacological, and neuroscience aspects of substance abuse medicine. He served on the faculty of five medical schools, usually as full professor of medicine, pharmacology, and psychiatry. Since retirement his interests have included historical research on the achievements of several ancestors, including Paul Cushman, an Albany, New York potter (1767–1833); William Gilbert, a New York silversmith and civil servant (1746–1831); and now Richard Varick (1753–1831). An avid bridge player, he also enjoys travel and savoring the visual and performing arts with his wife of fifty years, with whom he lives in New York City.
