Umberto Nobile Umberto Nobile (] ; 21 January 1885 – 30 July 1978) was an Italian aviator, aeronautical engineer and Arctic explorer. Nobile was a developer and promoter of semi-rigid airships during the period between the two World Wars. He is primarily remembered for designing and piloting the airship "Norge", which may have been the first aircraft to reach the North Pole, and which was indisputably the first to fly across the polar ice cap from Europe to America. Nobile also designed and flew the "Italia," a second polar airship; this second expedition ended in a deadly crash and provoked an international rescue effort.
David Schwarz (aviation inventor) David Schwarz (Croatian: "David Švarc" , ] ; 20 December 1850 – 13 January 1897) was a Croatian-Hungarian aviation pioneer of Jewish descent born in the Austrian Empire. He is known for creating the first airship with a rigid hull, in his case one made entirely of metal, an essential step in creating a dirigible, that is: an airship whose flight trajectory can be fully controlled with the help of engine-driven propellers. 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).
