Gustave Buchet began his artistic training with four years of study at the École des Beaux-Arts in Geneva, where he was particularly influenced by Eugène Gilliard. From 1910-11 he attended, for four months, the Académie de la Grande Chaumiere in Paris and then returned back to Geneva. Here he founded along with Maurice Barraud and others, the group "Le Falot", the programmatic turned against the overwhelming power of Hodler school.

On a return visit to Paris in 1916-17, he came under the influence of the Futurists and created a series of images in the novel, provocative forms. Increasing hostility, even for his participation in Dadaist performances, led him in 1920 to leave Geneva and to move to Paris. There he developed a two-dimensional, geometric, tending to abstraction painting, which he successfully presented in solo shows in 1926 and 1929.

In 1931, he worked temporarily re-representational painting nudes and landscapes. 1940 made him the German advance to return to Switzerland, where he settled in Lausanne and in 1941 organized the first "Salon de Printemps". Buchet's contribution to the history of modern art was rewarded adequately in his home country only since the 1970s.
