Chief Petschauer was a senior enlisted crewman assigned to the USS Enterprise-E sometime in 2379 as a replacement for their lost crew.

Captain Wai-Lin Go, during her inspection tour, pointed out that Chief Petschauer had more reprimands than the ship had decks. (TNG novel: A Time for War, A Time for Peace)
