History.
Welch Allyn was founded in 1915 in Auburn, New York by Dr. Francis Welch and William Noah Allyn. Welch had received a patent for a hand-held, direct-illuminating opthalmoscope and convinced Allyn, a medical instruments salesman, to form a partnership. The company moved to Skaneateles Falls in 1953, where it is still headquartered today.
