Johnson Smith & Company

Johnson Smith & Company authored "The Book of Forbidden Knowledge," published in the early 20th century.

The company was known for producing novelty items and publications, often catering to popular interests of the time.

This book appears to be a compilation of various superstitions, folk beliefs, and purported magical practices from earlier periods, possibly dating back to the 18th and 19th centuries.

The author's approach seems to be more focused on collecting and presenting these ideas as curiosities rather than promoting them as genuine occult practices.

The book's content reflects the fascination with mysticism and the occult that was prevalent in certain circles during that era.
