Pierre Laurent Wantzel (5 June 1814 in Paris – 21 May 1848 in Paris) was a French mathematician who proved that several ancient geometric problems were impossible to solve using only compass and straightedge.[1]
In a paper from 1837,[2] Wantzel proved that the problems of
are impossible to solve if one uses only compass and straightedge. In the same paper he also solved the problem of determining which regular polygons are constructible:
- a regular polygon is constructible if and only if the number of its sides is the product of a power of two and any number of distinct Fermat primes (i.e. that the sufficient conditions given by Carl Friedrich Gauss are also necessary)
The solution to these problems had been sought for thousands of years, particularly by the ancient Greeks.
"Ordinarily he worked evenings, not lying down until late; then he read, and took only a few hours of trouble sleep, making alternately wrong use of coffee and opium, and taking his meals at irregular hours until he was married. He put unlimited trust in his constitution, very strong by nature, which he taunted at pleasure by all sorts of abuse. He brought sadness to those who mourn his premature death." -- Adhémar Jean Claude Barré de Saint-Venant on the occasion of Wantzel's death.[3]
