In 1916, the Carnegie Corporation of America accepted a proposal from Nathaniel Potter, a doctor who intended to study treatments for diabetes. With a grant from Carnegie, he and his successor, William D. Sansum, refined insulin extraction and successfully injected the hormone into the first adult recipient in the U.S. The patient who received the dose was 51 years old and considered to be terminally ill. With the insulin treatments, he lived to be 90. By 1923, insulin was a commonly used and highly depended on treatment for diabetes.
