Sacha Sosno, an artist associated with the Nice School, was born in Marseille in 1937. He grew up between Riga and Nice, where Henri Matisse was his neighbor in 1948. In Paris in 1958, he enrolled at Sciences Po, the School of Oriental Languages, the Faculty of Law, and the Film Institute at the Sorbonne.

Returning to Nice in 1961, he founded the magazine "Sud-Communications" and articulated the first theory of the "Nice School." After his military service, between 1967 and 1969, he turned to media, working as an author, columnist, and war correspondent.

Returning to art with obliterated photographs, a concept he developed into sculpture and architecture, Sacha Sosno created "obliterated" works featuring openings to see through, following the principle of "Hiding to See Better." He played with voids and solids, questioning archetypes and the unconscious.

Sacha Sosno is renowned for his square heads and in 2002 completed the first inhabited giant sculpture in Nice. Knighted in 2001, he has had his works permanently exhibited in several galleries since 2017.
