Arthur Constantin Krebs

Arthur Constantin Krebs (16 November 1850 – 22 March 1935) was a French officer and pioneer in automotive engineering.

Collaborating with Charles Renard, Krebs piloted the first fully controlled free-flight made in the French Army airship La France, which was designed in 1884. The flight covered 8 km (5.0 mi) in 23 minutes. The flight landed back at its starting point. On its seven flights the La France dirigible returned five times to its starting point.

Krebs and Renard shared the 1886 Ponti prize of the French Académie des sciences for their contribution to aerostation.

Krebs inspired Jules Verne. In Verne's 1886 novel Robur The Conqueror, he writes of "the striking experiments of Captain Krebs and Captain Renard".

In 1888 Krebs and Gustave Zédé designed the first modern French submarine, the Gymnote. The submarine was fitted with the first naval periscope and the first naval electric gyrocompass. The latter allowed the Gymnote to force a naval block in 1890.

From 1884 to 1897 Arthur Krebs modernized the Ville de Paris fire department; not only its equipment but its organisation as well. His work left a lasting impression in this elite corps.

In May 1896 Arthur Krebs patented a new automobile, fitted with an electromagnetic gearbox and a layout of the front wheels which re-centred them when the steering wheel was left alone. Today this is known as the Castor angle. The Panhard et Levassor company acquired a license to build 500 cars under the name of Clement-Panhard between 1898 and 1902 featuring this innovation.

Krebs succeeded Levassor as Panhard et Levassor's general manager from 1897 to 1916. He transformed the Panhard et Levassor Company into one of the largest and most profitable automobile manufacturers before World War I.
