Born into a Hungarian family in the Czechoslovak town of Kosice (now Slovakia), the four-year-old future artist reached Buenos Aires by ship in 1928. Although he grew up in Argentina, Kosice was already in his youth very much part of the artistic milieu of exiled artists in Buenos Aires. He forged ties of friendship with Grete Stern, Horacio Coppola, Clément Moreau and other artists. These relationships proved very beneficial for his artistic development, as he himself testifies in his autobiography:
“First-hand knowledge [got from Grete Stern] of the work of masters such as Moholy Nagy, Josef Albers, Kandinsky in his Bauhaus period, and even architects and designers such as Walter Gropius and Marcel Breuer had a special impact on me. The tendency towards abstraction that had prevailed in Bauhaus production was especially dear to my own ideas. I felt those masters who had worked in the stormy 1920s in Germany and who had scattered their creativity around the world after the Nazi closure of the School as part of my artistic lineage” (Kosice 2010, 39–40).
A pioneer of new art forms, and identifying himself with the concrete art movement, he brought together a group of artists who would exhibit their work at several events. The first exhibition mounted by the group took place in October 1945 at the home of Dr. Enrique Pichon Rivière, in Avenida Santa Fe. Two months later, a second show was held at Grete Stern's house in Ramos Mejia. Renate Schottelius, who had belonged to Truppe 38, the theatre company founded by Clément Moreau, was also a member of the Kosice group, and was involved on both occasions, performing her choreographies.
Today, Kosice’s house has become a museum open to the public. It regularly offers activities for both children and adults. Moreover, Casa-museo Kosice offers visitors the possibility to see inside one of the traditional houses of the Buenos Aires Almagro district.
