Karl Ludwig Waldemar Geest

Geest's Möwe VI

Dr. Karl Ludwig Waldemar Geest was an aero inventor and company founder. He and his firm built monoplanes apparently following a Mowe patent; a monoplane, 1913; and, apparently, a prototype 1-seat fighter, 1916, that appears to have been produced by Aviatik, 1917. We are assuming for now that "Waldemar Geest" in patent data refers to this person.

American patent data has full-name Karl Ludwig Waldemar Geest as “a subject of the king of Prussia”, 5 Schyrenstrasse, Munich, Germany, and with Alois Wolfmüller appearing among witnesses to a patent filed by Geest.

British patent data has him as a “Doctor of Medicine”, 5 Schyrenstrasse, “Munchen” (properly München, anglophone Munich, that is), Germany.

Geest seems to have essentially one extended patent family, with one German patent, and its addition within the German system, the international spread largely reflecting relations analogous to this.
