Lewis Albert Sayre.

Lewis Albert Sayre (1820-1900) was an American pioneer in the field of orthopedic surgery, and medicine in general. In addition to much work on spinal and other deformities, Sayre was a founder of what later became the New York University Medical School, where he headed the first department of orthopedics in the United States. Sayre also was a charter member of the American Medical Association and served as its vice president and later as president. He was instrumental in developing the Journal of the American Medical Association, and his extensive work as Resident Physician of New York City led to improvements in sanitation, vaccination, and quarantine for smallpox and cholera.
