Dear Lyce: Thank you for all the additional information. I have known some of those facts especially about his interest in coins and stamps. It is a pity that he isolated himself, my father had very vague memories of him.
His brother Charles was another interesting person. You may be aware that he was a noted scientist, specializing in the field of herpetology.
They were a talented family. Please keep me informed of any other information you may uncover and I would be happy to help you in any way that I can.
