Adolf Repsold
Adolf Repsold (born August 31, 1806 in Hamburg ; † March 13, 1871 there ) was a syringe master and designer of optical instruments in Hamburg.
Life
Adolf Repsold was the son of Johann Georg Repsold . After his father died in a fire on January 14, 1830, Adolf Repsold and his brother Georg took over his father's business. The company was now called A. & G. Repsold , later A. Repsold & Sons . Even more than the father's company, the brothers focused on the design and construction of optical, especially astronomical, instruments. Since his brother was involved in his own roofing business, the main burden lay with Adolf Repsold.
Like his father, Adolf Repsold was a syringe foreman in Hamburg, who had to organize a fire team in the event of a fire. On May 5, 1842, the Hamburg fire broke out in Deichstrasse , which destroyed a large part of Hamburg's inner city in the following 4 days. It was not until the town hall was blown that the necessary firebreak was created to stop the flames.
In 1856 Adolf Repsold became senior syringe master. Two years later he set up the Central Bureau of Extinguishing in his house . In 1858 his son Johann Adolf became a partner in the company.
In 1867 Adolf Repsold left the company, while his third son Oscar was taken in at the same time .
Work
The first major task was the completion of the circle dividing machine, which Johann Georg Repsold had started in 1818, for the precise production of line marks on the setting circles of the optical devices. A. & G. Repsold developed into one of the most respected optical companies of the time.
