Frank Preston Stearns (1846–1917), the son of abolitionist George Luther Stearns, was a writer and abolitionist from Massachusetts during the 19th century. In addition to collaborating with Elizur Wright in ambitious abolitionist projects, such as the American Anti-Slavery Society, he is credited with several seminal works exploring the lives and careers of important American public figures and authors of note, including The Life and Genius of Nathaniel Hawthorne, The Life of Prince Otto von Bismarck, and The Life and Public Services of George Luther Stearns.
