# Mathematician:Édouard Lucas

## Mathematician

French mathematician best known for his study of the Fibonacci numbers. As a result of his researches, discovered what are now known as the Lucas numbers.

In $1876$, proved that the Mersenne number $M_{127}$ is prime, and discovered that $M_{67}$ is actually composite.

Discovered a method of determining the primality of a Mersenne number. This technique was refined in the $1930$s by Derrick Henry Lehmer and became known as the Lucas-Lehmer Test.
