The success of "This Is Tomorrow" secured Hamilton further teaching assignments in particular at the Royal College of Art from 1957 to 1961, where he promoted David Hockney and Peter Blake. During this period Hamilton was also very active in the Campaign for Nuclear Disarmament and produced a work parodying the then leader of the Labour Party Hugh Gaitskell for rejecting a policy of unilateral nuclear disarmament. In the early 1960s he received a grant from the Arts Council to investigate the condition of the Kurt Schwitters Merzbau in Cumbria. The research eventually resulted in Hamilton organising the preservation of the work by relocating it to the Hatton Gallery in Newcastle University Fine Art Department.
