1st Officer is a fictional character who appeared in the Hogan's Heroes episode, The Scientist. He was played by Forrest Compton. The 1st Officer first appeared in the episode as one of the two German officers whom Colonel Hogan saw through the sink periscope, after the prisoners of Barracks 2 have been told, through Schultz, Kommandant Klink's orders not to look through any of the barracks' windows and door, and that they are being confined to barracks until further notice. Hogan sees him and his fellow officer leading a civilian, later found out to be Henry DuBois, a French synthetic fuel expert, towards the storage building which the prisoners have cleaned out earlier that week.
