R. F. (Robert Frederick) Foster

Born in Edinburgh on May 31, 1853, he was educated as an architect and civil engineer before emigrating to the United States, probably in the early 1870s. After work in surveying, prospecting, and manufacturing, he moved into memory-training ventures and eventually built a long career as a writer and editor focused on games.

He wrote more than 50 nonfiction books, mainly about card, dice, and board games, and became especially influential in whist and bridge. He also served as card editor for the New York Sun and later for the New York Tribune, helping shape how a wide readership learned and discussed these games.

His best-known book, Foster's Complete Hoyle, first appeared in 1897 and gathered the rules and play of more than 100 indoor games into one widely used reference. By the 1930s he was described as a leading bridge authority, and his reputation lasted well beyond his lifetime. He died on December 25, 1945, in Eastham, Massachusetts.
