Under the Microscope:
The History of a Hamburg Family
More than 200 years – a long time for a company’s history.
The family enterprise of A. Krüss spent these last two centuries
keeping up with the breathtaking developments in
science, technology, optics and precision engineering. An
amazing number of high-precision optical and other quite
different products have been shipped world-wide from the
Hamburg laboratories. Although
some have long since been forgotten,
more recent products, are known
throughout the world.
But let us return to the origins, to
1796 and the Hamburg workshop of
Edmund Gabory, “Mechanicus
Opticus“. Gabory was trained in
London by none other than Jesse
Ramsden, the world famous optician,
at a time when precision engineering
was flourishing. On finishing his
training in 1790, Edmund set up a
workshop of his own in London
Holborn. In 1796 he moved with his
family to Hamburg, the international
port city and trading centre. This is
where the talented optical engineer
established his career and saw his
business prosper. When Gabory died in 1813, the company
was taken over by his widow Mary and their son Edmund
Nicolas. In 1823 Gabory’s daughter Mary Ann married
Andres Krüss.
The combination of scientific skill with Hanseatic business
acumen, tradition and perspective proved to be a successful
formula. Together with his wife and her brother, Andres
Krüss led the company to further success, adding nautical
instruments and charts to their product range. Brisk trade
with the neighboring Scandinavian and other foreign
countries developed. In 1844 Andres Krüss established a
company of his own named Optical Institute A. Krüss. Four
years later he fell victim to one of the cholera epidemics.
After his death, the company was first run by his widow,
who then handed it over to her sons Edmund and William
in 1851.
In 1859 Edmund set up the company’s own lens-grinding
facility. In addition to camera lenses, they later manufactured
special magic lanterns equipped with two objectives
for “dissolving views“: A mechanism made the projection
of the first slide disappear while the second image appeared.
In order to demonstrate the quality of his photographic
lenses he opened his own photographic studio. He
was awarded first prize for his lenses at the World Exhibi-
Andres Krüss,
Founder of the optical institute A. Krüss
tion in London in 1862. In 1865 Krüss patented his famous
“Magic Lantern“, forerunner of the cinema projector.
Still in existence at this time, the original company of
Edmund Gabory was merged with Optical Institute A. Krüss
in 1886. Edmund‘s son Hugo returned to take over the
management of the company in 1888 after completing his
training with distinction at the optical
factory of Steinheil and his university
studies in Munich. In a period of many
new inventions and scientific developments,
Dr. Hugo Krüss established
himself as a pioneer in theoretical and
applied photometry. His Manual of
Electromechanical Photometry became
a standard work. In his capacity
as Chairman of the German Society
for Precision Engineering and Optics,
Dr. Krüss was appointed by the
German government as an expert for
customs and excise in 1892; while in
office, he convinced the government
to establish a tariff heading specifically
for “scientific instruments“. In
1917 the Hamburg Senate awarded
Dr. Krüss a professorship in recognition
of his achievements in the scientific world and his
engagement in public affairs.
In 1904 Hugo’s son, Dr. Paul Krüss joined the family company
at the age of only 24. The so-called “master craftsman
with a doctorate“ managed the company from 1920,
through the troubled times of crisis and World War, as well
as during the later restructuring of the German economy.
Using his international connections in the world of science,
he developed a range of scientific instruments including
laboratory equipment for schools.
Andres Krüss, Paul’s son, was an engineer and became a
partner in 1946 in the 5 th generation. Due to his hard
work during the “German Economic Miracle“, Andres secured
new customers and new markets. Dr. Paul Krüss died
in 1976 at the age of 96. No one else had ever run the
company so long.
Today the company is run in the 6 th generation by Martina
Krüss-Leibrock, who took over A. Krüss in 1980. Martina is
the daughter of Andres who died in 1992. And today the
company A. Krüss remains famous for high-precision, stateof-
the-art measuring instruments. Thus the traditional
craftsman’s art of precision engineering has been perfectly
combined with innovative electronic technology.
