A fragment from a notepad with brief notes (pencil) on the Crick family business, and a single page (p. 6), photocopied from an unidentified source, headed "The beginning of mechanised shoe-making". The page includes an illustration of "an early 'Blake' sole-sewing machine" and describes something of the history of the Crick family business, including the technique of "inside riveting" for which the family took out a patent.
In What Mad Pursuit (1988), Crick recalls (p. 7): "My parents ... were a middle-class couple living near the town of Northampton, in the English Midlands. The main industry in Northampton in those days revolved around leather and the manufacture of footwear - so much so that the local soccer team was called the Cobblers. My father [Harry], with his eldest brother, Walter, ran a factory, founded by their father, that produced boots and shoes."
