Late 1656 the physicist Christiaan Huygens invented the pendulum clock, which is still considered as very important. As to implement his invention, Huygens sought collaboration with master clockmaker Salomon Coster in the Hague. From that moment on Coster became the most influential clockmaker in the Netherlands.

Because relatively little was known about Salomon Coster, Rob together with Victor Kersing started an archive research on Salomon Coster. Their goal is to map the story of Coster and his family.
