In the 1920s Leeds College of Art was the starting point for the careers of the sculptors Barbara Hepworth and Henry Moore, and in the 1950s, and 1960s it was one of the leading centres for radical art education in Britain under the guidance of artists such as Harry Thubron and Tom Hudson, and the art historian Norbert Lynton. Their attempts to redefine what art education should mean in the post-Second World War period led the artist Patrick Heron to claim in 1971 in "The Guardian" newspaper that "Leeds is the most influential art school in Europe since the Bauhaus". This willingness to push at the boundaries of acceptable public behaviour from artists was also evident in 1966 when Leeds College of Art staged an exhibition of paintings by the Cypriot artist Stass Paraskos, who taught at the college, which was raided by the police after allegations of obscenity.
