In 1949, Jean Crotti made a significant mark on the art world with his painting « Naissance d’un tourbillon » (Birth of a Whirlpool), introducing the concept of gyratory rhythm into his work. This pivotal moment marked the launch of his “Cosmic” series, where he revisited and expanded upon themes from his canvases of 1921 and 1922.

Crotti’s fascination with the mystery of the stars and the celestial vault is unmistakable. He boldly expressed this intrigue by integrating gyratory rhythms into his paintings, vividly depicting the dynamic motion of planets orbiting the sun.

On March 2, 1957, the gemmail decoration at the Franklin-Roosevelt metro station in Paris was inaugurated, and it continues to be a prominent feature to this day. Jean Crotti passed away in Paris on January 30, 1958, and he is interred at the Saint-Léonard cemetery in Fribourg, Switzerland.
