Although the historical record is unclear, it appears that Grasshoff originally trained to pilot two-seat observation aircraft, and by November 1916 as an Oberleutnant he was assigned to Jasta 15 as a single-seater pilot, based at Habsheim.

According to Udet’s biography, translated into English under the title Ace of the Iron Cross, on 4 June 1917: “I write to Grasshoff, an old friend from the days at Habsheim -- ‘I want to go to another front, I would like to come to you. I’m the last of Jasta 15, the last of those once left from Mülhausen to go to Champagne.”
