Chester K. Steele

"Chester K. Steele" was a pseudonym of the Stratemeyer Syndicate, founded by Edwin Stratemayer. The Stratemeyer Syndicate was the producer of a number of series for children and adults at the beginning of the twentieth-century. They pioneered the technique of producing long-running, consistent series of books using a team of freelance authors to write standardised novels. The novels were published under various pen names owned by Stratemayer's company.
