English landscape-painter, born in Sunderland, of Irish descent; began as a scene-painter; his first picture, "Market-boats on the Scheldt," proving a success, he devoted himself to easel-painting, and his principal works were "Wreckers off Fort Rouge," "A Calm at Sea," "The Abandoned," "The Bass Rock"; his frequent visits to the Continent supplied him with fresh subjects; and Ruskin says of one of his pictures, "it shows as much concentrated knowledge of the sea and sky as, diluted, would have lasted any of the old masters for life" (1793-1866).
