Théodore Clovis Edmond Lemartin, known as Léon Lemartin, was a pioneer aviator who set a world record on 3 February 1911 at Pau, France when he carried seven passengers in a Blériot XIII Aerobus. He then took eight, eleven and thirteen passengers aloft the following month. He is also known as the world's first professional test pilot.

The Blériot XIII was an experimental passenger-carrying aircraft built during 1910 by Recherches Aéronautique Louis Blériot. It is notable for setting a record for passenger carrying flights, and was probably intended as a developmental aircraft for the Blériot XXIV Limousine.
