Frank Haddock (1853-1915) was an influential New Thought and self-help author, best known for his series, The Power-Book Library. He graduated from St. Lawrence University in 1876 and began training for the Methodist ministry, but decided to pursue a law career instead. He was admitted to the bar in 1881 and moved to Milwaukee, Wisconsin, where he established himself as an attorney.

In 1887, his father was assassinated in Sioux City, Iowa due to his connection to the temperance movement. After his father’s death, Frank returned to the church and worked as a minister in Iowa, Ohio, and Massachusetts.

Haddock retired from the ministry to become a writer. As a New Thought author and lecturer, he became well known for his teachings on will power, cultivation of the will, ethics, financial and business success, philosophy, and spirituality. Like his contemporaries William Atkinson and Charles Haanel, he exemplified the more secular and less overtly religious side of the New Thought movement.

Frank Haddock died in Meriden, Connecticut on February 9th, 1915, at the age of 62. The cause of death was meningitis, at that time a virtually untreatable disease. He was just completing his final work, The Creative Personality at the time of his death, and it was published posthumously.
