I'm doing a presentation later this year on the role Agnew Hunter Bahnson Jr. played in founding the Institute of Field Physics at the University of North Carolina at Chapel Hill. On a recent trip to the Philadelphia Museum of Art, I lucked onto a painting, ("The Agnew Clinic" by Thomas Eakins), of Bahnson's namesake, Dr. David Hayes Agnew . Dr. Agnew was the long time friend of Bahnson's grandfather and performed the excision of his elbow joint. Thomas Eakins is a famous American painter who lived in the Philadelphia area. The "Agnew Clinic" was his largest painting. The picture below is of another painting by Thomas Eakins.
