1941
Despite the personal discomfort expressed in letters to Italian friends, Fontana began to receive growing recognition from both the public and art critics.
1942
At the same time, he began his career as a teacher, teaching modeling at the Escuela de Artes Plásticas in Rosario de Santa Fe and decoration at the Academia de Bellas Artes "Prilidiano Pueyrredón" in Buenos Aires.
1943
He established himself in the upper-class circles of Buenos Aires, moving his studio to Calle Esmeralda. In Italy, Tullio d'Albisola published an illustrated story with fourteen drawings by Fontana.
1944
He continued to distinguish himself in art exhibitions: he participated in the XXXIV Salón Nacional de Bellas Artes in Buenos Aires, winning the first municipal prize with the work Mujer herida. He also exhibited at the IV Salón Municipal de Pintura y Escultura in Cordova.
1945
An intense summer for Fontana: he organized a solo exhibition at Impulso, near Buenos Aires, and participated in the exhibition Once escultores argentinos at the Museo Provincial de Bellas Artes in La Plata. With the work La mujer de Lot he took part in the Salón Independiente in Buenos Aires, an alternative to the official national salon.
He obtained the chair of modeling at the Escuela Nacional de Bellas Artes "Manuel Belgrano" and moved his studio to Calle Chancos, to a larger space.
1946
He promoted in Buenos Aires the Altamira School, attended by young people from the Madí Group, born from the concretist movement led by Tomás Maldonado. In the same year the monograph by Juan Zocchi on his Argentine work was published.
The Argentine context: Arte Madí and Arte Concreta
During his third Argentine stay (1940-1947), Fontana lived in an effervescent cultural milieu that profoundly influenced the birth of Spatialism. The context was dominated by movements of radical renewal:
The Arturo Group and the Manifiesto Invencionista
The magazine Arturo (1944), with a cover by Tomás Maldonado, contained illustrations by Kandinsky, Mondrian, and Torres García. The manifesto proclaimed: "Art will be only tension and pure image, aesthetic vibration" and "Abstract art will guarantee a multidimensional harmony, without the needs for psychological adaptation".
Edgar Bayley, the group's poet, wrote the Manifiesto Invencionista (1946), dominated by historical materialism and a Hegelian-Marxist idea oriented toward spiritual and social progress. The manifesto advocated detachment from the primitivist myth in favor of a sign of pure invention: "Don't search or find, Invent".
The Madí Movement
In August 1946, Gyula Kosice founded the Madí Group, which claimed greater inventive freedom. Kosice developed the sculpture Royi: wooden elements assembled as vectors in space that affirmed the importance of void over mass and required the presence of the viewer.
In his magazine Arte Madí Universale, Kosice wanted Fontana's participation. In his autobiography, he advanced the hypothesis that all of Fontana's art, especially from the Manifiesto Blanco onward, had been influenced by the insights of the Madí movement in relation to the desire to go beyond two-dimensionality to embrace space and light.
The Asociación Arte Concreto Invención
In 1946 Maldonado founded the Arte Concreto Invención Association. The manifesto stated: "A poem or a painting must help man act within his society". The idea was that of an art that adapted form and expression to technological progress, rejecting speculative aesthetics in favor of a "scientific aesthetics".
Fontana's dual nature
This stay in Buenos Aires gave Fontana an impulse that cross-pollinated the insights matured in Europe, freeing them of all normative residue. The new Argentine art aimed at the free creation of forms and a positive idea of history, very distant from Fautrier's dead bodies, Burri's wounds, the suffering spirit of European Informel.
1947
He renewed his collaboration with rationalist architects, creating polychrome ceramic friezes for a building at via Senato 11, designed by Marco Zanuso and Roberto Menghi.
1948
In March he published the second Spatialist manifesto, also signed by Gianni Dova and Antonino Tullier. In spring he participated in the National Exhibition of Figurative Arts in Rome with a large ceramic sculpture, Il Guerriero.
He was also present at the exhibition Abstract Art in Italy and at the XXIV Venice Biennale, where he exhibited an abstract sculpture, three ceramic works, and one in mosaic. His sculptural research, strongly material, resumed the studies of the thirties, anticipating "informal" outcomes. He established his new studio at via Prina.
1949
He continued in the funerary field with the Angel in polychrome ceramic for the Chinelli tomb, designed by Renzo Zavanella at the Monumental Cemetery of Milan. He initiated a collaboration with Arredamenti Borsani for ceilings, lamps, and ceramic furnishing objects. He began a period of intense travel among Italian and European cities.
1950
In May he held a solo exhibition of ceramics at the Galleria il Milione and participated in the XXV Venice Art Biennale. He took part in the competition for the fifth door of the Milan Cathedral.
