Artist in watercolour, pastel, oil and gouache, born in Aberdeen. Hardie was a self-taught artist with a fine sense of colour in the Scottish tradition, who painted mainly landscapes, latterly still life and portraits. He obtained his master’s degree from Aberdeen University in 1931, became a Bachelor of Science in 1934 and obtained his doctorate in 1959. After time as a research engineer with Metropolitan Vickers, then commissioned service in the Royal Air Force, 1939–46, Hardie lectured in electronics at Aberdeen University and was professor of physics at the University of Bath. He was elected RWA in 1970 and was a member of the Bristol Savages. He showed with Aberdeen Artists’ Society, RSA and had several solo exhibitions, including Rooksmoor Gallery and Holburne Museum, both in Bath, at RWA and at Logie Gallery, Tain, in Ross-shire, where he settled at Cromarty.
