Painter, constructions artist and teacher, born at Devonside, Clackmannanshire. Dingwall studied at Edinburgh College of Art, 1955–9. After being an Andrew Grant Postgraduate Scholar, 1959–60 and living in Greece, 1961–2, Dingwall began teaching at Edinburgh College of Art in 1963. From 1973–4 he was visiting professor at Minneapolis College of Art and Design in America. In 1988 he was appointed professor at the Cleveland Institute of Art, Ohio. It was from around 1973 that Dingwall developed his abstract paintings and constructions, influenced through work seen in America by Mark Rothko and Robert Ryman. Dingwall’s method of painting was laborious and careful, usually in sombre colours, his aim being to reveal shifts between what we feel and what we reveal.
