David Schwarz (aviation inventor)

David Schwarz (Hungarian: Schwarz Dávid; Croatian: David Švarc, pronounced [dǎʋit ʃʋârt͡s]; 20 December 1850 – 13 January 1897) was a Hungarian aviation pioneer. He is known for creating an airship with a rigid envelope made entirely of metal. Schwarz died only months before the airship was flown. Some sources have claimed that Count Ferdinand Graf von Zeppelin purchased Schwarz's airship patent from his widow, a claim which has been disputed. He was the father of the opera and operetta soprano Vera Schwarz (1888–1964).
