Yom de Saint-Phalle was born in Paris in 1970.Very Early he learns modeling and painting, then studies political science and journalism.
At the age of 24, he stops painting and get enrolled in the Legion Etrangere. In 2001, after more than 6 years in combat units all over the world, from Africa to the Balkans, he leaves the Legion Etrangere.
Back in France, his aunt, Niki de Saint-Phalle, invites him to come to California with her and perfect his artistic training.He enters into the world of sculpture as a welder; later on he shows an interest for mosaic, and finally composite materials. After the death of Niki de Saint-Phalle, he dedicates himself to his own creativity and pursue his training with Raymond Hains in Paris from 2002 to 2005.
Deeply impacted by the absurdity of the war, Yom develops an original approach of sculpture that emphasizes the absence of material more than the material itself.
Yom currently leaves and works in Paris, but travels a lot in order to show his work to art collectors all over the world.
