About the author
Born in Sullivan, New Hampshire, on January 22, 1830, Rufus Osgood Mason was trained as a physician and surgeon. Sources available here describe him as a doctor, teacher, and writer who later became known for exploring hypnotism, suggestion, and what was then called psychical research.
Mason is especially remembered for popularizing these subjects for general readers rather than keeping them only within specialist circles. His career sits at an interesting crossroads: he had a conventional medical background, yet he became associated with early efforts to understand mind, influence, and unusual mental phenomena.
He died in New York City on May 11, 1903. A confirmed portrait image was not available from the source page I could check here, so no profile image is included.
