Jakob Haw was an aero inventor in Berlin-Schöneberg, filing patents in Hungary and France as well as Germany, generally to do with the design of propeller blades.
Hungarian patent data gives Haw as an Engineer (Mérnök) filing from Potsdam, Germany.[1]
He did some filing in collaboration, on the airship, with the lesser-known Arthur Sauer.[2][3]
Haw continued to file patents for propellers in the 1920s, and expanded his reach to include Great Britain and the United States. On his British filings[4] he gives no occupation per se, instead describing himself as a German citizen or German national. He gives the address 16, Stierstrasse, Berlin-Friedenau.
