Lambert, Edward Howard (born 1915), and Eaton, Lealdes McKendree (1905–1958), American physicians. Lambert and Eaton spent the bulk of their careers at the Mayo Clinic in Rochester, Minnesota. At the Mayo Medical School Lambert served for many years as professor of physiology and in later years also as professor of neurology. Eaton rose to the position of professor of neurology and head of the Clinic's neurologic section. Lambert's areas of research included neurophysiology, electromyography, and various human neuromuscular disorders. Eaton's own research topics included myasthenia gravis and polymyositis. Lambert and Eaton were the principal authors of a 1956 article describing the syndrome which now bears their names.
