Almost exclusively animalier, very familiar to monumental scale, Le Bourgeois received an early training in the restoration studio of his father, who worked for the Historical Monuments Institute and who shared his passion for medieval art.

After 1910, Gaston was noticed by important Parisian patrons, like Jacques Doucet at the Salon des Artistes Décorateurs where he exhibited curious wooden pillars with cats at the top. In this Salon, he usually presented wooden panels with animals and this decorative taste leads him to collaborate with Henri Rapin met in 1915 and with who he took part in the Sèvres Manufacture Pavillon at the International Decorative Arts Exhibition in 1925.

The graphic and geometrical lines of his animals are clearly related to the Art Deco aspirations, which spread forms with Cubism. The artist’s researches are closed to the ones of the Martel brothers, with who he also collaborated for the Chapel in the Normandie Liner.

The most appreciated material of this sculptor is wood, which he used for decorative sculptures, furnitures on which he added fine low relief. He was also interested by architectural elements like capitals or stairs pillars. Most of his sculptures should be seen with a profile point of view, which enhanced the archaic inspiration of his models.
