John Falconar Slater was a Northumbrian artist who exhibited prolifically in his own area. Initially, however, he worked as a bookkeeper for his father's corn mill and then ran a store in the diamond fields of South Africa before turning to art as a career. He was a member of the Bewick Club and President of the North East Art Club, based in Whitley Bay, and also a member of the Cullercoats Colony. He is recognised as being one of the earliest British artists to adopt the Impressionist technique of painting. He was expert at depicting the many moods of the North Sea. The last twelve years of his life were spent in Cullercoats.
Exhibited: L. 5, M. 1, R.A. 22 and widely on Tyneside.
His work is held at the National Maritime Museum, Laing Art Gallery, Newcastle and Shipley Art Gallery, Gateshead.
