In 1956, coinciding with the exhibition Modern Art in the United States at Tate, three painters of the New Vision Group – Denis Bowen, Halima Nalecz and Frank Avray Wilson – founded New Vision Centre Gallery in Seymour Place. Its policy was to show young non-figurative artists, with a special interest in Tachisme and Art Informel. Under the direction of Bowen, it soon became a platform for artists exploring progressive ideas, with the exhibition of Enrico Castellani and Piero Manzoni in 1960 and the survey of the German-based Group Zero in 1964, which was organised with the art critic Kenneth Coutts-Smith in collaboration with McRoberts and Tunnard Gallery. Bowen staged around 250 shows over a ten-year period, many of them either first solo events or London debuts. At a time when solo shows of contemporary foreign artists were not common, the gallery was one of the first to embrace internationalism in the arts, exhibiting artists from 29 countries, with an emphasis on those from the Commonwealth, including Aubrey Williams and Anwar Jalal Shemza.
