Ruth Derham’s Bertrand’s Brother: The Marriages, Morals and Misdemeanours of Frank, 2nd Earl Russell (Amberley Publishing, 2021) recounts the life of the close friend of Santayana’s youth Frank Russell. Santayana’s autobiography, Persons and Places (1944, 1945, and 1953) PDF EPUB, was an important source for understanding the life of Frank; and Derham’s engaging book, in turn, provides enlightening personal and cultural context for understanding Santayana’s life and his friendships with both Frank and his brother.
