Person: Lucas, François Édouard Anatole
Edouard Lucas was a French mathematician who is best known for his results in number theory. He studied the Fibonacci sequence and devised the test for Mersenne primes still used today.
Mathematical Profile (Excerpt):
 During the FrancoPrussian War (18701871) Lucas served as an artillery officer.
 After the French were defeated, Lucas became professor of mathematics at the Lycée Saint Louis in Paris.
 Lucas is best known for his results in number theory: in particular he studied the Fibonacci sequence and the associated Lucas sequence is named after him.
 Lucas also devised methods of testing primality, essentially those used today.
 The Lucas test for primes was refined by Lehmer in 1930.
 Lucas is also well known for his invention of the Tower of Hanoi puzzle and other mathematical recreations.
 Lucas died as the result of a freak accident at a banquet when a plate was dropped and a piece flew up and cut his cheek.
Born 4 April 1842, Amiens, France. Died 3 October 1891, Paris, France.
