Winterthur will host the upcoming lecture, Unlikely Friends: H.F. duPont and Dr. Albert Barnes, on Tuesday, April 6, from 6 to 7 p.m. Registration is required. The lecture is $15 or $10 for members. The former home of Henry Francis duPont, famous antiques collector and horticulturist is located at 5105 Kennett Pike, Winterthur, Del., just south of Chadds Ford, Pa., and just north of Wilmington, Del. DuPont focused on fine antiques, while Barnes preferred modern art and folk art. What could they possibly have in common? Witherthur estate historian Jeff Groff attempts to shed light on the shared interests of these world-renowned collectors while also exploring duPonts other connections to the world of modern art from the 1930s to the 1950s.
