Donati was one of the organizers of the Exposition Internationale du Surréalisme held in Paris in the summer of 1947, to which he contributed a painting and two sculptures. In the late 1940s he responded to the crisis in Surrealism by going through a Constructivist phase, from which he developed a calligraphic style and drew onto melted tar, or diluted paint with turpentine. He also became associated with Spatialism, founded by Lucio Fontana. Thus began his long fascination with surface and texture, including mixing paint with dust, that culminated in the 1950s in his Moonscapes, a series that has similarities with the work of Dubuffet. The fossil became a major theme for Donati through the 1960s, and he gave new importance to color in his Fossil works, for example in Red Yellow Fossil (1964; Miami, Hills Col., see Selz, p. 19). In 1961, he was given a major retrospective at the Palais des Beaux-Arts in Brussels and frequently exhibited at group shows in the USA and elsewhere. He held a number of important teaching and advisory posts, including Visiting Lecturer at Yale University (1962–1972).Wikipedia
Jacques Hurtubise (1939–2014) was a Canadian abstract painter, "known for his abstract, brightly coloured acrylic paintings"
Hurtubise was born on February 28, 1939 in Montreal, and studied painting at the École des beaux-arts de Montréal. Already by 1960, at age 21, he had his first major show at the Montreal Museum of Fine Arts.He spent much of the 1960s living in New York City and becoming part of the abstract expressionist scene there His art at that time combined geometric forms with splashed paint, and he experimented with fluorescent colors and neon light art.In the early 1970s his compositions were based on square forms, but by the late 1970s they shifted to linear patterns that resembled abstract landscapes.His later work featured "deep-black pools, rivers and geometric forms that often mask upside-down maps and text."Wikipedia
