I couldn't find any indication that he owned a drugstore, except for the
drugstgore bottle shown below.
His WW-I draft card listed him has a doctor practicing in "Port Royal &
Vicinity". He shows up in the 1920 US Census as a physician living in
Port Royal, but the 1930 US Census lists him living in Fredericksburg
VA, which is about 20 miles away from Port Royal. So my guess is that
he had some type of drugstore in Port Royal starting by 1917, and ending
sometime between 1920 and 1930, but that's just a guess.
In 1919, he was promoted from lieutenant to captain in the Medical Corps
U.S. Army, where he served overseas. 3
He retired in 1970. He was a Rotarian and an Elk, and a member of various
medical societies. 2
