The Hunterdon Review, Alison Jones stated, "My father, Winthrop H. Jones, was an architect and painter who constantly framed the world for me. He taught me to see details and graphic forms without my ever really knowing what was happening. It wasn't until I was in my forties that I realized that I had a natural sense of composition and a need to capture the way I saw the world". h Among Winthrop's employees was William Turnbull, of Moore Lyndon, Turnbull, Whittier, architects of Sea Ranch in northern California. Also
Lawrence C. Apgar Jr. An addition at the DuPont estate Winterthur in Delaware was a notable project in the office which Larry assisted Winthrop on. ==Military career==
