Amédée Mannheim
Victor Mayer Amédée Mannheim ( born July 17, 1831 in Paris, † December 11, 1906 ) was a French mathematician, engineer and officer. He developed the eponymous scale system for the slide rule.
Life
Amédée Mannheim 1848 began his studies at the École Polytechnique in Paris at the age of 17 years. Two years later he went to Metz at the Ecole d'application de l' artillery et du genie.
After graduating in Metz Mannheim was an officer in the French artillery. After a few years in the military Mannheim in 1859 to the École Polytechnique in Paris called, while he continued his army career. His first assignment was as a lecturer. In 1863 he was appointed auditor. The following year, Mannheim was appointed professor of descriptive geometry at the École polytechnique.
Mannheim ended his military career in 1890, after he had attained the rank of colonel in the engineering corps. He continued his education at the École polytechnique continued until he retired in 1901 to retire at the age of 70 years.
Work
While studying in Metz Mannheim developed in 1850 a new scale system for the slide rule has long been known. At the same time he also led the already known moving runners for a more accurate reading. Thus, he created the standard of the modern slide rule. Its scale arrangement of the slide rule became known as system Mannheim world.
Mannheim wrote numerous treatises on geometry. He studied the polar reciprocal transformation by Michel Chasles and its effect on the kinetic geometry. He also studied mathematical surfaces, especially Augustin Jean Fresnel wave surfaces.
