Life and horological achievement

Free spring escapement according to Ludwig Strasser

Ludwig Strasser was born in Würzburg on December 15, 1853. After attending primary school, he began an apprenticeship with the well-known master watchmaker Sebastian Geist as early as 1867, at the age of 13 . On the mediation of Karl Moritz Großmann he came to Glashütte in 1871 and worked in his workshop until 1873.

Then Strasser worked for a year in Leipzig at the tower clock factory B. Zachariä. In 1874 Strasser returned to Glashütte to take over the production of a watchman's control clock on behalf of the Leipzig company. In 1875, L. Strasser and the mechanic Gustav Rohde founded the mechanical workshops Strasser & Rohde , which manufactured measuring devices , precision pendulum clocks and marine chronometers of various types.

While working in his company, Strasser invented the "free spring escapement for precision pendulum clocks", later named and patented after him , which was one of the last developments in the field of mechanical precision pendulum clocks before the invention of the quartz clock. Other important works in the clock technology and precision engineering field are the likewise patented nickel steel compensation pendulum and the Strasser astronomical second pendulum clock "DUB".

On the initiative of his former employer Moritz Großmann, the founding of the German Watchmaking School of the Central Association of German Watchmakers in Glashütte was decided in 1877 at the German Watchmaking Conference in Wiesbaden. Strasser was a member of the preparatory committee.

As early as 1878 as a member of the supervisory board of the German Watchmaking School Glashütte, he was responsible for the control of theoretical lessons. One year after the establishment of the educational institution, he was entrusted by the supervisory board, headed by Moritz Großmann, with supporting teaching activities in theoretical lessons switched to school service. After the death of Moritz Großmann (January 23, 1885) and the director of the school Georg Heinrich Lindemann (March 29, 1885), the Supervisory Board appointed him provisionally at its meeting on April 17, 1885 and appointed him to the office of May 1, 1885 Director of the German Watchmaking School, which he then practiced until his death. He taught mathematics, theoretical mechanics, watchmaking theory, electrical engineering, drawing and bookkeeping. Due to the school activity, L. Strasser's work was limited to construction and control activities until he finally left the company in 1914.

In recognition of his outstanding achievements, Ludwig Strasser, a former elementary school student without a university education, was appointed Royal Saxon Professor on April 12, 1902. In 1910, his achievements were honored once more with the award of the Knight's Cross 1st Class of the Order of Albrecht.

In November 1914, at the age of 61, Strasser married Johanna Rose, a former graduate of the watchmaking school and daughter of Rose, a master watchmaker from Szczecin. Before the end of the First World War , Ludwig Strasser died after a long and serious illness on August 12, 1917 at the age of 63 in the city hospital in Dresden.

The Strasser & Rohde company existed in various forms until December 31, 1958.
