My husband (Yildirim Aktas) is Turkish and was educated by a Peace Corp volunteer in a small Turkish village (Plumer) in the mid-late 1960s, early 1970s. He would like very much to find this volunteer and thank him. He believes his name is David Vandergrist- but cannot recall for sure. Because this kind person, my husband went on to get his PhD in Physics and would like to touch base with his teacher. If anyone can assist me, I would be very appreciative.
