Mathematician:Gabriel Léon Jean Baptiste Lamé

Full name: Père de Gabriel Léon Jean Baptiste Lamé. (Sometimes misrepresented as "Gabrielle Lamé", but that is a mistake.)

French mathematician who investigated curvilinear coordinate systems.

Studied the series of curves now known as Lamé curves.

Generated a proof of a special case of Fermat's Last Theorem. He thought he had created a general proof for it, but it was flawed.

Worked on elasticity theory. The Lamé Parameters are his invention for describing the elasticity of a material.

Determined the running time for the Euclidean Algorithm, using Fibonacci numbers. This sequence of numbers is sometimes known as Lamé's sequence.
