Arthur Constantin Krebs ( November 16 , 1850 in Vesoul , France – March 22 1935 in Quimperlé , France ) was a French officer and pioneer in automotive engineering. Collaborating with the ''La France'' dirigible returned five times to its starting point. Krebs shares the 1886 Ponti price of the French ''Académie des sciences'', with Charles Renard, for their contribution to Aerostation. Krebs inspired Jules Verne in his novel ''Robur The Conqueror'' in 1886 , when he tells "the striking experiments of Captains Krebs and Renard". In in 1890 . From 1884 to 1897 Arthur Krebs modernized the ''Ville de Paris'' fire department, its equipment as well as its organization. His work left a lasting impression in this elite corps until today. In May 1896 Arthur Krebs patented a new automobile, fitted with an electromagnetic gearbox and a front train coming back straight when the steering wheel was left. Panhard-Levassor acquired a license, and built 500 cars under the name of Clement-Panhard between 1898 and 1902 . Krebs succeeded to Levassor as Panhard-Levassor 's General Manager from 1897 to 1916 . He turned the Panhard-Levassor Company as one of the largest and profitable manufacturer of automobiles before WWI. In 1902 he invented the first automatic diaphragm carburetor giving to cars continuous accelerations in assuring at any time a constant air-gasoline rate and so reducing dramatically cars gasoline consumption. In 1906 Krebs went to the USA to plead in the Selden affair, jointed to Henry Ford . He introduced many improvements in car design : the steering wheel ( 1898 ), the irreversible steering ( 1898 ), balance of engines ( 1898 ), nickel steels and other special steels ( 1901 ), shock absorber ( 1906 ), multi-disc clutch ( 1907 ), the electric dynamometric brake for high speed engines power measurement ( 1905 ), the globic worm screw differential ( 1915 ). Thus Krebs contributed to improve the Systeme Panhard quite universally adopted before WWII. In 1909 , he believes in the interest of the Knight patent ( Sleeve-valve Engine ) and first in France build that type of engine which Panhard-Levassor will produce during 30 years, until the WWII. He contributed in the automotive sport with his powerful racing cars and racing motorboats. In 1911 Krebs invented the first elastomeric Flexible Coupling (cf. John Piotrowski ). It is known in french as the ''Flector'' joint. This device is still widely used today in the industry for power transmission as ''tyre coupling''. For military and civil purposes, he designed in 1911 , with the Chatillon cy, the all-terrain truck named ''Tracteur Chatillon-Panhard'', which was four wheels drive and four wheels steering. Many of these trucks had been used during the WWI as artillery tractor. He utilized his former military membership to supply the French Army with engines and vehicules dedicated to Aerostation , Submarine s, Aviation , the 1904 Genty Armored Car , The 1916 St Chamond Tank , the ''Chatillon-Panhard'' 4x4 Truck etc. COMMUNICATIONS TO THE FRENCH ''ACADéMIE DES SCIENCES''
Several months before his death, the French government awarded Arthur Krebs the badge of Commandeur of the Legion of Honor in 1934 for his work in Aerostation and his automotive industry contribution. SEE ALSO
