He graduated from the University of Michigan in 1904 and trained at University of Michigan (with AS Warthin); Boston City Hospital; Harvard (with W.T. Councilman and F.B.

Living in the highly industrialized city of Pittsburgh which at that time was the most smoke polluted city in the US, he was acutely aware of the effects of air pollutants on the human lung. His investigations on this subject led to many important publications on the pneumoconioses – anthracosis and silicosis. His nonmedical interests included amateur plays and music.
