Hilger Crystals Ltd ~ History
Hilger were founded in 1874 by two German precision optical instrument technicians Adam and Otto Hilger. They fled Germany a few years previous to escape religious persecution and en route to England worked for a short time for the French physicist Foucalt whose work on the precessing motion of a pendulum gave an insight into the fundamental understanding of the earth's rotation.
