Legendre != Legendre

Adrien-Marie Legendre foi um matemático francês que viveu no fim do século XVIII e início do século XIX. Contribuiu para diversos campos da rainha das ciências e usualmente o identificamos por esta fotografia:


Certo? Errado. Esta é, na verdade, uma fotografia do político francês, anterior ao Legendre matemático, Louis Legendre. O único e verdadeiro retrato que temos do Legendre que nos interessa é, de fato, uma caricatura. Onde ele aparece sisudo ao lado de outro matemático igualmente icônico, o (gorducho e sorridente) Joseph Fourier:


O mal-entendido foi solucionado em 2007 pelo professor Gerard P. Michon em seu site Numericana, mas veio a tona novamente em um artigo de Peter Duren chamado Changing Faces: The Mistaken Portrait of Legendre publicado na edição de Dezembro de 2009 da revista Notices of the American Mathematical Society.
