The Norgaard Hospital was located at 1505 Fifth Street South. It was in operation from 1909 to 1922. According to a Fargo Forum article at that time, the Hospital was described as taking medical and surgical cases and open to the public. I don't have a picture of it.
Ragnhild Norgaard was listed as the proprietor. According to census records, she was 70 in 1920, and the widow of Torgus Norgaard. Her daughter Sondrine, who was 43 in 1920, is listed either as a nurse at Norgaard Hospital, or as the superintendent. The building is no longer there. In its place is a 1950's vintage building that houses Luther Hall, a facility for troubled teens.
