World Famous Surgeon
Developer of the Percy System of Whole Blood Transfusion
I find it just fascinating that a world famous doctor was the product of such a small town and its public school. And that he is the man credited with coming up with the idea of transfusing blood directly from one person to another!
Dr. Nelson Percy
(1875-1958)
Nelson Mortimer Percy was born in Dexter, Iowa, in 1875 to Mortimer and Mary (Amidon) Percy. (Both parents are buried at Dexter). Nelson attended Dexter public schools, graduating in 1892.
Founded in 1868, Dexter is a small town in central Iowa, in the southwest corner of Dallas County. The town’s population never exceeded 790 souls. When Nelson Percy was in high school there, Dexter had only 607 residents.
And yet, this young man went on to medical college. In 1899 he graduated Rush Medical College and interned at Augustana Hospital, becoming assistant to the chief surgeon, Dr. Albert J. Ochsner. The two men published Clinical Surgery in 1912. Dr. Percy became chief surgeon there in 1925, and chief of staff in 1935. He perfected the Percy Method of Whole Blood Transfusion (consisting of running a tube directly from the donor’s vein to the person needing blood), used by Chicago hospitals before WWII.
Dr. Percy was also a professor of clinical surgery at the University of Illinois.
During WWI, Dr. Percy organized the US Base Hospital No. 11 in France, serving as Lieutenant Colonel, Medical Corps. He was surgical director there.

He became President of the Chicago Surgical Association in 1925, and also head of the American Goiter Association.

He became Chief of Staff at the Augustana Hospital, Chicago in 1936.

A fascinating account.
I’m actually having these handy for the Dexter Museum in a small Iowa town!
Small towns are the best towns 🙂
What a remarkable story!
Impressive man. Hope the town is proud of its native son.
Me too, but Dexter is more noted for being the town where Bonnie and Clyde shopped for a few days before the shootout in Dexfield Park in 1933!
