Inventors and engineers who made clocks, watches, telescopes, microscopes and other instruments of accurate measurement, from ancient water clocks to the pendulum clock and the marine chronometer. A person belongs here when the cited article credits the person with a timekeeping or measuring instrument. It excludes designers of engines and weapons, who sit in their own groups. The group is one of the groupings of engineers under this engineering field in the Technology Atlas, and each member keeps its own entry with its own cited sources and its own place in the field.
