(b Rotherhithe, 1633; d 1704). English clockmaker. After an early career as an anchorsmith and blacksmith, he turned in 1677 to clock-making, initially specializing in turret clocks (e.g. clock of 1671 for Chapel of King's College, Cambridge, now in the Science Museum, London). He subsequently became a maker of fine long-case clocks, which he fitted with the anchor escapement (of which he may have been the inventor) and a screw regulation of the pendulum; many have the long 1¼-second pendulum. This ‘royal pendulum’ length allowed a minute and second hand to be fitted to the clock face alongside the hour hand that had previously been the only hand on the face.
