H.J. Kummer explained: These clocks which are able to measure tertia are standard equipment for every observatory ... The instruments were usually delivered with a certificate by the national physico-technical institute... Most of them were used for military purposes. About 350 of these precision instruments were produced.
Franz Ludwig Loebner was born in Torgau in 1836; after having finished school, he began an apprenticeship with local master watchmaker Otto. His journeyman years took Loebner first to Leipzig and finally to Berlin, where he became a master watchmaker and started his own workshop in 1862. Loebners own design and construction efforts were always dedicated to time interval measuring instruments such as tertiae counters or a clock with a dial diameter of 3 m that measures milliseconds (illustrated in the Deutsche Uhrmacherzeitung of 1895). One of his last creations was the so-called "perpetual calendar" in the reading room of the German Reichstag; this was a clock which showed days, date, months, the turn of the year and the moon phases. The clock also had a perpetual calendar for the next 2000 years. In 1897 Loebner transferred his company to Otto Fritz. He died 1921 in Berlin.
