H. W. (Harland William) Long

Harland William Long (1869–1943), often published as H. W. Long, was an American physician and writer. He is chiefly known for Sane Sex Life and Sane Sex Living, a book that approached sex education, marriage, and procreation in a straightforward, instructional way.

The book was published in the early 1900s and has remained the work most closely associated with his name. Public-domain and library records consistently identify him as both the author and a medical doctor, suggesting he wrote from a professional as well as popular-educational perspective.

Beyond that, readily available biographical details appear to be scarce. What remains clear is that Long addressed a topic that many publishers and readers of his era treated cautiously, and that has helped keep his name in circulation long after his lifetime.
