When our family left Greenwich and confronted the things that would be dispersed, Brandeis sent an archivist and we filled about 20 boxes from the house and later my office in New York. They now reside in what I’m assured is a place that will keep them intact. They are not digitized. To access them for any purpose, I would start with Chlose Gerson (or a successor) at 781-737-4657. Or write email@example.com for information.
