Son of an ornamental sculptor, François-Raoul Larche studied at the Ecole des Beaux-Arts, where he became a Falguière and Delaplanche's student. After starting at the 1884 Salon, he was awarded the Second Prix de Rome in 1886. 
He exhibited several of his sculptures at the Salon, including La Tempête et les Nuées, which was a great success thanks to the sculptor's ability to animate the bronze with such expressive movements.

Larche was also asked to work on official commissions, such as the fountain at the Grand Palais, La Seine et ses affluents, which was originally intended to decorate the Carrousel gardens. 
Victim of a road accident in Paris on 3 June 1912, he died of his injuries the same day.
