Color woodcut artist who had an international reputation in the 1920s and 1930s.The son of a silversmith, he was born in Hampstead, London. When he was eight, his father died and he moved with his mother to East Sussex, first to Bexhill-on-Sea, then to Winchelsea, and finally, in 1929, to Seaford. He attended the Hastings School of Art. Notable for their beautifully observed skies, many of Slater's prints are inspired by the South Downs and the coastline near his home.
His printmaking was revered during his relatively short career, and much admired by Campbell Dodgson, then Keeper of Prints and Drawings at the British Museum. Slater was a member of the Society of Graver Printers in Colour and the Society of Print Makers of California. His work was exhibited in Canada, Australia, New Zealand, Austria and South Africa, but he stopped making woodcuts soon after the death of his mother in 1938.
By the time Slater died in 1963, he had sunk into obscurity. With no close surviving relatives, he was buried in a shared grave in Seaford. An exhibition helped revive interest in his work and the output of other British artists who used Japanese techniques to make color woodcuts - a printing method introduced to the United Kingdom by Frank Morley Fletcher (1866-1949) in the 1890s.
