The highlighted building in the upper left is the Plant Hospital. This was a fully staffed hospital with an operating room. The principal mission of the hospital was the medical care of employees but was also available to family members for limited medical needs except obstetrics which the hospital was not staffed or equipped for.
Ground view photo, taken in 1944, of the Hospital looking southwest at the main entrance. In front of the car at the left of the photo is the very large window of the operating room. The window is frosted glass so it lets in light but you can not see through it.
This photo was taken in the operating room in late 1951 when the Plant was reactivating for the Korean War. This was a state of the art facility at the time.
