Wilhelm Krumsiek was a well-known German aviation pioneer, particularly for the 1912-1914 years.
One machine flew in 1909, and crashed sometimes later.
After having built a second airplane, he became in 1912 chef pilot at the “Zentrale für Aviatik Karl Caspar” (Hansa), and flew with success at a number of competitions (Prinz-Heinrich Flug 1913, duration world record for monoplanes, etc…)
