Dr. Hugh Butt of Rochester, who was the last link between the Mayo brothers and the current staff of the famed medical facility in Rochester, died of natural causes after a fall on Aug. 16. He was 98.
Butt, who began his residency at Mayo in 1934, became a gastroenterologist, researcher, physician, teacher and administrator.
He was a Minnesota pioneer in his specialty. During his residency, he discovered that vitamin K stopped bleeding in patients with jaundice, previously a fatal condition.
His work changed the practice of hepatology, the branch of medicine that incorporates the study and management of disorders of the liver, gallbladder, biliary tree and pancreas.
Dr. Glenn Forbes, CEO of Mayo Clinic Rochester, said in a news release that Butt "brought a mixture of appreciation for our history with the drive for continuing the legacy into success in tomorrow's world."
Forbes said Butt was the last assistant to work directly with William Mayo, M.D., a founder of the clinic, and one who benefited from Butt's vitamin K research.
In 1997, Butt recalled how Dr. Mayo, who was jaundiced after surgery to treat cancer, thanked him for saving his life.
Over the years, Butt's inquiries into blood coagulation later made possible open heart surgery and organ transplants.
