author
1846–1917
A Scottish-born physician, soldier, and historian, he wrote widely on military subjects and regional history before publishing a substantial history of Nantucket in 1914. His work reflects a restless, wide-ranging career that moved between medicine, the military, and historical writing.

by R. A. (Robert Alexander) Douglas-Lithgow
Born in 1846, Robert Alexander Douglas-Lithgow became known as a physician as well as a writer of history and military subjects. Library of Congress records identify him as the author of Nantucket; a history, published in New York in 1914, and give his full name and life dates as 1846–1917.
Douglas-Lithgow seems to have had notably broad interests. In addition to his historical writing, surviving catalog and bookseller records connect his name with military and biographical works, suggesting a career shaped by both professional service and a deep interest in the past.
He died in 1917. Today, he is chiefly remembered through his books, especially Nantucket; a history, which remains the work most readily associated with his name in major library records.
