Traian Vuia or Trajan Vuia (Romanian pronunciation: [tra'jan 'vuja]; August 17, 1872 – September 3, 1950) was a Romanian inventor and aviation pioneer who designed, built and tested the first tractor monoplane.
He was the first to demonstrate that a flying machine could rise into the air by running on wheels on an ordinary road.
He is credited with a powered hop of 11 m (36 ft) made on March 18, 1906, and he later claimed a powered hop of 24 m (79 ft).
Though unsuccessful in sustained flight, Vuia's invention influenced Louis Blériot in designing monoplanes.
Later, Vuia also designed helicopters.
A French citizen from 1918, Vuia led the Romanians (especially Transylvanians) of France in the Resistance during World War II.
He returned to Romania just before his death in 1950.
