This signed letter dated January 3, 1924 is from Roosevelt to Professor McAdie of the Blue Hill Observatory in Mattapan, Massachusetts. It was composed during a relative quiet period for Roosevelt, between his stint as Assistant Secretary for the Navy (1913-19) and his term as Governor of New York (1929-32). The letter thanks McAdie for a book he sent Roosevelt, along with a recounting of how the British Navy caught the German fleet in the North Sea during World War I (based upon his classified knowledge as Assistant Secretary for the Navy). McAdie was a Professor of Meteorology at Harvard and the "little book" Roosevelt mentions is possibly his War Weather Vignettes first published in 1925. A nice example that demonstrates Roosevelt's passion for naval history.
