This is Joseph Hofmann‎‎, or more properly in German Josef Hofmann. Though "J. Hofmann" is found on the original document, the Lilienthal museum sight Objekt gives "Hofmann, Josef". Various cross-referenced patent data has confirmed for us that "J. Hofmann" is Joseph Hofmann. The Lilienthal museum sight Objekt for this patent gives the patent title "Neuerung an Flugmaschinen" while the associated Digitalisat display of the original patent document gives "Flugmaschine mit Luftbehälter". The The Objekt for this patent gives the filing date 1906-01-02 while the associated Digitalisat gives 1906-01-03.

The original twice gives the national patent classification we would write as DE 77h.6, with that on the first pencilled out and replaced with something along the lines of "Klasse 62c. Gruppe 15/...", with perhaps even a further stage of subclassification. This happens on several Hofmann patents.
