Winthrop Neilson was also an accomplished painter (oil, water color and more: http://www.rogallery.com/Neilson/Neilson_hm.htm). He started painting in his twenties while biking through Southern France with a paint box on his back. While visiting Rome he came up with his linear style. He lived in Buck Hill Falls, PA and for fifteen years at the National Arts Club in New York City. Additional information can be found on the Winthrop & Frances Neilson Fan Page in Facebook.
