1809–1887
A restless 19th-century reformer, lecturer, and publisher, he became one of the best-known American champions of phrenology and helped spark the brief craze for octagon houses. His books promised self-improvement, healthier living, and practical advice for everyday life.

by O. S. (Orson Squire) Fowler, L. N. (Lorenzo Niles) Fowler
Born in Cohocton, New York, in 1809, he studied at Amherst College and rose to prominence in the 1830s and 1840s as a lecturer on phrenology, the once-popular belief that character could be read from the shape of the skull. With his brother Lorenzo Niles Fowler and their publishing business, he reached a wide audience through lectures, manuals, and popular self-help writing.
He wrote on an unusually broad range of subjects, including health, sexuality, marriage, domestic life, and personal development. That mix of reform-minded enthusiasm and practical instruction made him a distinctive voice in 19th-century American print culture, even though many of the ideas he promoted, especially phrenology, are now regarded as pseudoscience.
He is also remembered for promoting the octagon house, which he argued was healthier, more efficient, and better suited to modern living than standard rectangular homes. Fowler died in 1887, but he remains an intriguing figure for the way he blended publishing, reform movements, and bold confidence in better ways to live.
