Frederick Charles Pybus

Frederick Charles Pybus DCL, FRCS (2 November 1883 – 10 March 1975) was an English surgeon from Newcastle-on-Tyne, who contributed to research into organ transplantation.

Research In July 1916, Pybus reported an attempt at allogenic transplantation of pancreatic tissue. Despite a mild reduction in glucose excretion in one of two diabetic patients transplanted with fragments of human cadaveric pancreatic tissue., both patients subsequently died.

Pybus concluded that:...although transplants represented the most rational form of therapy, they would continue to fail as long as science did not understand the principles involved.
