Do you know of any American numismatists who were also accomplished in the field of chess? I have:

Ben Franklin, not a numismatist, but numismatically important for his coin legends and the printing of paper money;

Daniel W. Fiske, an assistant librarian at the Astor Library, NYC, in the late 1850s and an important numismatist,

Fred Reinfeld (1910-1960), a popular writer on chess (mostly) and coins, and

S.W. Brown, a Shreveport rare dealer in the 1980s who was also a regional chess champion.

This is for a chapter in a book I am doing, about Sage and his Paul Morphy token.

The personal preferences and habits of historical, numismatic, and other people are seldom recorded. For example, while we know of some White House pets (Fala the dog, Socks the cat), we have no clue as to the type of toothpaste, beer, shoes, etc., that presidents preferred.

Many numismatists over the years have enjoyed and have even become prominent in non-numismatic activities and hobbies, but such are little recorded. One dealer was an avid big-game hunter, another a race car driver, another an important collector of stamps, etc., and so it goes.

John Dale Beety was a junior chess champion. I believe my American Numismatic Biographies is one of few sources that mention other interests of numismatists.
