He studied at the School of Fine Arts in Chisināu and emigrated to Belgium where he studied at the Royal Academy of Brussels. In 1926, he moved permanently to Paris where he worked in the studio of Wlerick and Arnold. Painter "fawn" of the School of Paris, he actively participates in the artistic life of Montparnasse. He was inspired by Matisse whom he admired. Color was for him a tool of ex- pression and was a language loaded with emotions. He was noticed by critics as early as 1929, most notably by Waldemar George, editor-in-chief of the magazine Prime des Arts. He participates in group exhibitions at major Parisian exhibitions and exhibits alone at the Galerie Katia Granoff, the "Qua- tre Chemins", and the Armand Drouant Gallery. Later, he made two important solo exhibitions at the André Weil Gallery, Avenue Matignon, which were a great success and were warmly welcomed by critics. During WW2 Irisse remained in Paris but, denounced as Jewish by one of his suppliers. He had to hide to escape the Gestapo. His beloved mother was caught in a raid in 1942, deported and murdered in Auschwitz. His painting, ful of poetry, is a hymn to light, color, joy of living. He brilliantly combined bright, bold, brilliant colors, simplified theperspective, and left the forms only very bare lines.
