The Hipp Chronoscope - continued...


The successor firm of Peyer & Favarger, the FAVAG, continued to produce chronoscopes. In the late 1920s, FAVAG still offered Hipp chronoscopes similar to type "88" without any major modifications. Even after the second world war, FAVAG offered chronoscopes. These precision time measuring devices, called "synchronous chronoscopes," relied on a completely different technology, however. Synchronous motors for 110 or 220 volts replaced Hipp's lamella escapement driven by mechanical force.

As of today, 107 Hipp chronoscopes have been identified. Five of them are only mentioned in the literature. But signature, serial number, and/or description prove that these instruments existed. Unfortunately, nobody knows where they are kept. 17 of the still existing Hipp chronoscopes are in private collections. The majority of the other surviving chronoscopes are located in the collections and museums of psychological institutes. Only a few can be found in clock museums.

To protect all the old chronoscopes listed in the full version of this paper (see PDF-download, below), the information about their location has been shortened to a minimum. All scientists, psychologists, historians and other persons who need more detailed information for their research may obtain the desired information from Rand Evans, Henning Schmidgen, or the author.

Update: On October 15, 2003, the police has given back the stolen chronoscope to the University of Bonn (more details). In the meantime, a few other chronoscopes have been discovered. The total of still existing chronoscopes is 118 now. Please, contact us if you have any knowledge of other unknown chronoscopes of the Hipp style.
