# Charles Hermite

**Charles Hermite** (pronounced "air MEET") (

1822 -

1901) was a French mathematician who did research on

number theory, quadratic forms,

invariant theory,

orthogonal polynomials,

elliptic functions, and

algebra. The

Hermite polynomials are named in his honor. He was the first to prove that

*e*, the base of natural logarithms, is a

transcendental number. His methods were later used by

Lindemann for the proof of his celebrated theorem that

&pi is transcendental.
