A contributor with a limited biographical record
The 1911 title page names Dr. Franklin L. Dubois as a co-author with A. Gould. The retained preface to the ninth edition uses the spelling Duboise and credits him with supplying material based on his experiences and investigations. This establishes a contribution to the expanded book, without identifying precisely which passages he wrote.
His life dates, education and professional appointments remain uncertain. The title Dr. is part of the publication’s attribution; it does not by itself establish his qualifications or a medical practice. Later publishing records also use Du Bois.
Sexual restraint and regeneration
The held tenth edition was issued by Advanced Thought Publishing Company in Chicago, with a 1911 copyright and London representatives named on the title page. It presents sexual energy as a resource that can be conserved and redirected toward health, self-command and spiritual growth. Its chapters combine discussion of reproduction and marriage with occult theories of evolution and consciousness.
The preface appeals especially to readers seeking strength, concentration and success. The wider text makes extensive claims about illness, sexual conduct and rejuvenation, framing restraint as both a moral duty and a route to renewal. These are historical assertions within the book’s programme. Its medical language and promise of scientific instruction should not be taken as evidence that the proposed regenerative effects were demonstrated.
