Hiller Aircraft - Wikipedia
History. Stanley Hiller, then seventeen, established the first helicopter factory on the West Coast of the United States, located in Berkeley, California, in 1942, under the name "Hiller Industries," to develop his design for the coaxial-rotor XH-44 "Hiller-Copter" for the U.S. Army. The XH-44 became operational in 1944. In collaboration with Henry J. Kaiser, it became United Helicopters in 1945.
