Werner Voss was a World War I German flying ace credited with 48 aerial victories. A dyer's son from Krefeld, he was a patriotic young man while still in school. He began his military career in November 1914 as a 17‑year‑old Hussar. After turning to aviation, he proved to be a natural pilot. After flight school and six months in a bomber unit, he joined a newly formed fighter squadron, Jagdstaffel 2 on 21 November 1916. There he befriended Manfred von Richthofen.

Krefeld, also spelled Crefeld until 1925, is a city in North Rhine-Westphalia, Germany. It is located northwest of Düsseldorf, its center lying just a few kilometers to the west of the river Rhine; the borough of Uerdingen is situated directly on the Rhine. Because of its economic past, Krefeld is often referred to as the "Velvet and Silk City". It is accessed by the autobahns A57 (Cologne–Nijmegen) and A44 (Aachen–Düsseldorf–Dortmund–Kassel).
