Joseph Hofmann was an aero inventor in Berlin, often recorded it seems as J. Hofmann who is probably the same person.

However there is a gap between the british patents and the german and US ones in time so maybe it's two different people. To do: figure it out!

Patents whose inventor or applicant is Joseph Hofmann or J. Hofmann
Patents whose inventor or applicant is J. Hofmann
