Notes

In the advertisement for his clocks Jacob describes himself as a pupil of Berthoud and Breguet. Jacob became famous for his one year-going clocks, which were very rare before the last quarter of the 19th century. They became popular only after the invention of the torsion pendulum. From the mid-18th Century, regulators started to be made by clockmakers not only for observatories but for their own use to set watches and for many of the important houses and country estates. These ?domestic? regulators frequently employed wood rod pendulums with heavy brass bobs. The wood rod pendulum was ideal because, being wood, it was unaffected by changes in temperature, therefore other compensation devices could be fitted ? usually less expensive to make than a compensated metal pendulum. Wood rod pendulums were used on most Vienna wall regulators for this reason.
