I had little luck looking for the 135 or 125 General Hospital.No alumni group and no hits on google.Also checked US Army Military History Institute to no avail.
The US Army must have a historical section attached to its medical corps??I think most branches have a museum etc...
With that in mind I did locate the office of Medical History via the office of the Surgeon General.Here is the link and email address for inquiries. http://www.armymedicine.army.mil/history/http://www.armymedicine.army.mil/history/ John.Greenwood@otsg.amedd.army.mil
ALSO the home of ARMY medicine is at Fort Sam Houston.
