He first exhibited at the National Academy of Design in 1866 and continued to exhibit his paintings there until 1897 and was elected a member of the Artists’ Fund Society of New York in 1873. That spring, he sailed for England, as his brother had four years earlier. Finding success in London, he decided to remain, renting a studio on Newman Street and exhibiting two paintings at the Royal Academy in 1875. In 1876, the artist visited the Swiss Lakes and Northern Italy, making many sketches. Parton painted in both the Tonalist mood of Corot (1796-1875) and in the Barbizon style, the latter of which he more fully embraced and is more closely associated. While in London, he met and became close friends with fellow American artists Theodore Robinson, John Singer Sargent, Daniel Ridgeway Knight, and Henry Bacon.
