For advice re the medical equipment, get in touch w/ the Bakken Library of Electricity in Life, 3537 Zenith Avenue South, Minneapolis, Minnesota 55416; (612)927-6508. They have a first-rate collection of medical devices through the 1940s, and their curatorial staff is knowledgeable and helpful. The New York Academy of Medicine may also be helpful in this area; I'm not certain, though, as I've not had direct experience with them myself. --Bayla [log in to unmask]
