Irving Innerfield

Irving Innerfield (died 4 December 1976) was a medical researcher in the United States of America. A specialist in inflammation, he discovered that the enzyme Trypsin could be used to dissolve blood clots.

In November 1952, on hearing that Sister Elizabeth Kenny (the Australian who developed physical therapy as an effective treatment for polio and established many clinics for polio victims in the USA using her methods) was dying in Toowoomba, Queensland, Australia from a cerebral thrombosis, Innerfield dispatched his experimental drug based on Typsin by air to Brisbane to treat her thrombosis. Unfortunately Kenny was close to death when the drug arrived and was administered, dying the following day.
