Alberto Magnelli (1 July 1888 – 20 April 1971) was an Italian modern painter who was a significant figure in the post-war Concrete art movement.
Magnelli was born in Florence on July 1, 1888. In 1907 he started painting and, despite lacking formal art education, by 1909 he was established enough to be included in the Venice Biennale. His initial works were in a Fauvist style. Magnelli joined the Florentine avant-garde befriending artists including Ardengo Soffici and Gino Severini. He also visited Paris where he met Guillaume Apollinaire and the Cubists including Pablo Picasso, Fernand Léger and Alexander Archipenko.. By 1915 had adopted an abstract style incorporating cubist and futurist elements.
Over the next few years Magnelli returned to figurative work and drifted away from the Italian avant-garde, which was becoming more supportive of Fascism, which he opposed. By 1931 he had returned to abstraction in the form of concrete art featuring geometric shapes and overlapping planes. He moved to Paris, where he joined the Abstraction-Création group and became friend with Wassily Kandinsky, Jean Arp and Sophie Taeuber. Following the invasion of France by the Nazis, Magnelli went to live in Grasse with several other artists including the Arps. Some of the group, including Gerson, were Jewish so they were forced to hide. Despite this, the group was able to produce a number of collaborative works.
Following the World War II, Magnelli returned to Paris which was to be his home for the rest of his life. He became a major figure in the post war concrete art movement and influenced artists such as Victor Vasarely, Nicolas de Staël as well as the concrete artists in South America such as Hélio Oiticica. He again exhibited at the Venice Biennale, this time with a whole room. Major galleries organised retrospectives of his work.
Magnelli died on April 20, 1971 at his home in Meudon, France.
