Chasles, Michel


Born Nov. 15, 1793, in Epernon; died Dec. 18, 1880, in Paris. French mathematician and historian of mathematics. Member of the Académíe des Sciences (1851; corresponding member, 1839).

Chasles became a professor at the Ecole Polytechnique in Paris in 1841 and at the University of Paris in 1846. His most important works deal with geometry. He contributed to the development of projective geometry with, for example, his textbook Treatise on Higher Geometry (1852). Chasles’s works on the history of mathematics, particularly his Historical Survey of the Origin and Development of Geometric Methods (1837; Russian translation, vols. 1–2, 1883), helped establish the relations between individual studies and clarified the historical relationship of scientific ideas in the field.

Yet Lucas, who was born in 1818, did in fact manage to take in Michel Chasles in the 1860s, and as ludicrous as his inventions strike one now, they occupied the French Academy of Sciences in an extended wrangle at the time over the issue of Pascal's supposed priority in the discovery of the calculus among other issues, a priority unambiguously proven in some forged letters.
Contemporary obituaries of Michel Chasles (1793-1880) complete the book and help to prove, if further proof were ever required, that brilliance and folly are hot mutually exclusive in homo sapiens.
