Howard, John Eager (1902–1985), American internist and endocrinologist. Howard for most of his career was associated with Johns Hopkins Hospital, where he was director of the division of endocrinology and metabolism for many years. His early researches were concerned with the clinical syndrome associated with pheochromocytoma.
