author
b. 1858
A Methodist minister and educator, he wrote frankly about childhood, health, and moral development at a time when public discussion of those subjects was still unusual. His best-known book, Child Life and Sex Hygiene, reflects an early-20th-century effort to blend pastoral guidance with practical teaching.

by Otterbein Oscar Smith
Born in 1858 and later known as Rev. Otterbein Oscar Smith, he was a Methodist Episcopal clergyman whose work connected religion, education, and family life. Available records indicate that he died in 1934, and his published writing presents him as a minister deeply interested in the welfare and training of children.
Smith is best known for Child Life and Sex Hygiene, a book now available through Project Gutenberg. In it, he tackles questions of childhood development and sex education in a direct, instructive way that would have stood out in his era, aiming to help parents, teachers, and communities speak more honestly about subjects often treated with silence.
While not much biographical detail was easy to confirm, his surviving work suggests a writer who wanted moral instruction to be practical and compassionate rather than vague. For modern listeners, his books offer a window into how some early-1900s religious thinkers approached child welfare, education, and social reform.
