Fullerton L. (Fullerton Leonard) Waldo

Born in Cambridge, Massachusetts, on April 5, 1877, Fullerton Leonard Waldo was an American writer and editor. Available sources identify him as the son of Leonard and Dora (Fullerton) Waldo, and note that he later worked in Philadelphia.

Waldo is remembered especially as an editor for the Public Ledger in Philadelphia. His books show a wide range of interests, including With Grenfell on the Labrador, Grenfell: Knight-Errant of the North, America at the Front, and Good Housing That Pays: A Study of the Aims and the Accomplishment of the Octavia Hill Association, 1896–1917. Taken together, they suggest a writer drawn to public life, reform, travel, and firsthand observation.

He died on October 24, 1933, at age 56. I couldn't confirm a reliable portrait from the sources available here, so no profile image is included.
