Agostino Bonalumi, painter, after his technical studies, he was part of the fervent artistic environment in Milan from the late fifties onwards. In 1958 he exhibited alongside Piero Manzoni and Enrico Castellani at the Galleria Pater in Milan, his works were published in the magazine Azimuth, with just two issues released between 1959 and 1960, founded by Piero Manzoni and Enrico Castellani. He developed a language linked to the experiences of the Milanese artists gathered under the aegis of Lucio Fontana. He used monochrome canvases, often in very bright colours, in which the variations of light were given only by extroflections of the canvas itself. During the sixties he collaborated with Carlo Cardazzo's Galleria del Naviglio and with Arturo Schwarz, Gillo Dorfles wrote about his work and called the extroflections “painting-objects”.
In 1966 and 1986 he was invited to the Venice Biennale, in 1970 he had a personal room at the exhibition. He worked on various environmental works, in which large extroverted canvases directly shaped the environments, as well as sets and costumes for the theatre. He took part, among other things, in the Sao Paulo Bienniale in Brazil and the Paris Bienniale. In 1980 Palazzo Te in Mantua hosted an extensive monograph on his work, in 2001 he was awarded the President of the Republic Prize for Lifetime Achievement and a major exhibition was dedicated to him in Darmstadt in 2003. He actively participated in an exhibition in London, which he was unable to see open in 2013. In 2018, the Museo del Novecento in Milan organized an impressive retrospective on his work.
