Career
De Lambert was the first person in France to be taught to fly by Wilbur Wright. The first lesson took place at Le Mans on 28 October 1908. On 18 October 1909 de Lambert "left the Juvisy Aerodrome at 4:36 o"clock in a Wright machine, flew across Paris to the Eiffel Tower, circled it, and returned to his starting point, arriving safely at 5:25." De Lambert claimed that he flew 300 feet above the 1,000 foot Eiffel Tower, which was nearly equal to Orville Wright"s height record set in Berlin.
Lambert, along with Hubert Latham and Louis Blériot, was one of the three main contenders for the £1,000 prize offered by the Daily Mail for a successful crossing of the English Channel in an aèroplane, although he was not motivated by the monetary value.
He took his pair of Wright Flyers (Nos 2 and 18) and set up camp at Wissant to practice and wait for good weather. Latham made the first real attempt, but foundered and landed on the water, and Lambert damaged his "Flyers" while practising.
