American writer of popular historical biographies. Stone first came to prominence with the publication of Lust for Life (1934), a vivid fictionalized biography of the painter Vincent Van Gogh.

After receiving his B.A. in 1923 at the University of California, Berkeley, and his master's degree in 1924 from the University of Southern California, he wrote plays and supported himself by writing detective stories. In 1934—after being rejected by 17 publishers—Lust for Life was finally accepted and published.

Stone termed his work “bio-history.” Through meticulous and exhaustive research, he verified and expanded his preconception of a selected historical character. Then, by immersing himself in the subject's native environment and reading all available original documents, from letters and diaries to research notes and household accounts, he acquired the basis for imaginary or reconstructed dialogue.

In addition to Lust for Life, Stone's many popular works include Clarence Darrow for the Defense (1941); They Also Ran (1943), biographies of 19 defeated presidential candidates; Immortal Wife (1944), the story of Jesse Benton Frémont, wife of the explorer John Frémont; President's Lady (1951), based on the life of Rachel Jackson, wife of the seventh U.S. president; Love Is Eternal (1954), a fictionalized account of the marriage of Mary Todd and Abraham Lincoln; The Agony and the Ecstasy (1961), a life of the Renaissance artist Michelangelo; The Passions of the Mind (1971), about Sigmund Freud; and The Origin (1980), a life of Charles Darwin centred on the voyage of the Beagle and its aftermath.

Stone founded the Academy of American Poets in 1962, in addition to founding several other literary societies. He married Jean Factor, his editor from 1933, in 1934.
