The most prolific author in history may be Charles Hamilton (1876-1961), who could turn out 80,000 words a week writing long series of stories with recurring casts of characters, often set in boys’ public schools. Hamilton wrote under a variety of names and occasionally employed other writers to help with the work, but his own lifetime output has been estimated at 100 million words.

In his 1940 essay “Boys’ Weeklies,” George Orwell writes, “The stories in the Magnet are signed ‘Frank Richards’ and those in the Gem, ‘Martin Clifford’, but a series lasting thirty years could hardly be the work of the same person every week.”

He was forced to add a footnote: “This is quite incorrect. These stories have been written throughout the whole period by ‘Frank Richards’ and ‘Martin Clifford’, who are one and the same person!”
