French sculptor, designer, writer, editor, and exhibition organizer, born in Algiers. After studying architecture and engineering in Paris he became a friend of Le Corbusier and founded the periodical Architecture d'aujourd'hui. He took up sculpture in 1940, initially being influenced by Laurens. In 1949 he turned to abstract sculpture, and launched the periodical Art d'aujourd'hui, which ran until 1954. It was the first periodical to be devoted solely to abstract art. Bloc used a wide variety of materials and techniques in his work, but he is more important as an editor and exhibition organizer than as a creative artist. See also Groupe Espace.
