Otto Hillig (18741954) lived most of his life in Liberty, New York, and gained fame as a photographer and transatlantic flier. He also had a German-style castle constructed for him near Parksville, New York, and served one term in the New York State Assembly(Submitted on June 29, 2026.)
With his plane, he planned a transatlantic flight to Denmark (the homeland of his intended pilot, Holger Hoiriis), and then on to Germany. He named his plane "Liberty", as part of "repaying Liberty for its part in his good fortune." A local editor lauded this project for bringing great publicity to his adopted city .Hillig claimed he was making that expensive and risky flight "just for the fun of it" or "for the thrill". Hillig's modest goal was just "to be remembered pleasantly when I am remembered at all, as the man who flew the Atlantic and then came on back home and went to work."
Some highlights of Hillig's plane trip included getting an audience with the King of Denmark, and getting knighted. (King Christian was a "Brother Mason" to Hillig.) Despite the risks of flying there, he refused to load a radio or lifeboat on the plane, saving the room for gas. They ran out of gas on the flight over Germany, anyway, from having strayed off course in bad weather so, they had to land initially short of their objective, Denmark.
