This thesis studies the role of a craft guild as a training organisation. The study looks at the London Dyers’ Company binding and joining records over 150 years, available from the mid seventeenth century to the early nineteenth century. The study initially deals with transmission of knowledge from master to apprentice, a single generation. It then looks at factors associated with chains of transmission over several generations, taking advantage of available occupational specialization data.
The Dyers’ Company records of membership are estimated to be at least 94 percent complete from 1710-1792, and probably similarly complete in the earlier period 1660- 1710. In 1750, 93 percent and in 1792 81 percent of dyers in livery companies were members of the Dyers’ Company. In those same years, 34 percent in the livery of the Dyers’ Company were not practicing dyers.
