Dean Kamen invented the Autosyringe, the first practical insulin pump, 1979. I have Facebook friends who used that pump. Large and bulky compared to today's insulin pumps, but it helped way back then. Dean Kamen is a resident of New Hampshire. He has made many inventions. The Autosyringe is only one of them. He has a secret island off the coast of Connecticut with a structure containing some of his inventions. The second link below gives an interview with Dean, made for NBC TV.
