Amongst the many projects set up connected with the forthcoming centenary is a searchable database of all those hatched, matched and dispatched at Calais between 1914 and 1922, based upon the official registers held by the City Archives. It includes not just the native Calaisiens and Calaisiennes, but also Belgian, British and even German refugees and soldiers (not to mention a smattering of people from other countries from Portugal to Japan).
This is the first of a series of biographical sketches based on the research I am doing for my new book Kings of the Air: French aces and airmen of the Great War , to be published by Pen & Sword. Clément Ader (1841-1925) was a French inventor, whose attempt at heavier-than-air flight some years before the Wright brothers was so nearly successful. Ader had a restless mind, and his inventions covered a wide range of fields. In 1868, he began as a velocipede manufacturer. Instead of conventional iron tyres, his machines used a rubber tubular tyre of his own invention, resulting in a much lighter frame, and a much more comfortable ride. The war against German in 1870 brought an end to his work. He then began working for a railway company in the south-west of the country, the Compagnie des Chemins de Fer du Midi. In 1875, he designed an engine that laid rails, that saw service for several years. He then turned to the new telephone, commercialising the inventions
