Painter in acrylic and teacher, born in St Ives, Cornwall. His family moved to Banbury when he was young and he went to the Art School there, 1967–70, then Cardiff College of Art, 1970–3. Returned to live in Cornwall in 1974, at Morvah, with a studio in Penzance. He commonly worked to a background of Rock music and designed an album cover and backdrop in 1990 for the world tour of a favourite group, The Fall. Frost was much in demand as a teacher of colour to children. He said he wanted his own pictures “not to be influenced. I want them to be colour and shape. I don’t want people to see things in them … It’s like creating your own language.” Took part in many mixed exhibitions, solo shows including Newlyn Art Gallery, 1979, later ones Gordon Hepworth Gallery, Newton St Cyres, and Royal Cornwall Museum Galleries, Truro, both 1991.
