He became an influential art teacher. He was one of the first British artists to be influenced by the French Impressionists; he exhibited with the New English Art Club, and was an associate of many of the more progressive artists of late Victorian Britain, including James McNeill Whistler, Walter Sickert, John Singer Sargent and George Clausen.
