Abstract
Edward Cocker was a well-known writing master and engraver during his lifetime, but is chiefly remembered for his posthumous arithmetic textbook, immortalized in the saying `According to Cocker'. The book proved popular, being right for its time, and it remained in use for a century. It unexpectedly became the subject of controversy when Augustus De Morgan pronounced it to be the produce of its editor, John Hawkins. Research now shows that there is little doubt that it was really Cocker's work.
