Berthold Lubetkin had been offered Une vache by his friend Léger in 1932, but instead he opted to purchase it with Lucien Lefebvre in the same year. Lubetkin was one of the main proponents of Modernist Architecture in Britain. Born in Tiflis, Georgia, Russia in 1901, he studied in Russia, Berlin and Warsaw before settling in Paris, where he attended the Ecole des Beaux Arts. In Paris he observed the early experiments of Le Corbusier, and became friendly with the Purist circle of artists and architects, among them Fernand Léger. He established an architectural practice with Jean Ginsberg for a short time before moving to England in 1930. In 1932 he helped establish the Tecton Group and was actively involved with MARS (Modern Architectural Research Group) and CIAM (International Congress for Modern Architecture).
