# Euler's Number is Transcendental/Proof 2

## Theorem

Euler's Number $e$ is transcendental.

## Proof

$\blacksquare$

## Historical Note

The transcendental nature of Euler's number $e$ was conjectured by Joseph Liouville in $1844$, after he had proved that it was not the root of a quadratic equation with integer coefficients.

The proof that $e$ is transcendental was first achieved by Charles Hermite in $1873$.
