275 years of Siedle history

For 275 years, Siedle has been synonymous with pioneering building communication made in Baden-Württemberg – with deep roots in the Black Forest town of Furtwangen and a clear vision for the future. This is an impressive anniversary for one of Germany's longest-standing family businesses! My warmest congratulations on this milestone, and I wish you continued success, innovation and sustainable growth. Here's to the next 275 years!

Yours sincerely, Nicole Hoffmeister-Kraut

Minister for Economic Affairs, Labour and Tourism for the State of Baden-Württemberg

We not only look back at our interesting history here, but we also show the development of the company and our products in comparison with the generations that preceded them. And we publish exciting content about 275 years of Siedle throughout the year.

Every month, an organising committee surprises our staff with special anniversary celebrations. In February, for example, delicious doughnuts were served to mark Shrove Tuesday.

Portrait of a great businessman

1894-1976

The fifth son of Hektor Siedle lived and worked in New York, in Columbia, Switzerland, Holland and England before returning to Furtwangen and becoming CEO of S. Siedle & Söhne in 1951. The global citizen and pacifist was banned from working in 1944 because he was the only member of the Union of Electrical Wholesalers not to join the NSDAP Party. Like many Siedles, he had a strong artistic streak and devoted himself to painting in his free time.

1858–1926

Historian and innovator: Robert Siedle encouraged telephone and telegraph production, an innovation that was to ensure the company’s survival. He made a name for himself as a chronicler of his home country, his company and his family.

approx. 1900

with eight of her 16 children and their spouses. Her daughter, Karoline (6th from the left) was one of the first women in the company. Without any formal training, which was reserved for men, she managed to become a clerk and head of coil winding. But the company's shareholders were Salomon Siedle and sons - her father and brothers, who she also ran the household.

1830–1890

Founder, manufacturer, revolutionary: the son of Salomon I. joined the Baden Revolutionary Army in the fight against the Prussian troops. He introduced the transition to electrical engineering, founded the factory at its current location in 1870, and set up S. Siedle & Söhne in 1884.

1787–1857

The “Bregeme-Salomon” achieved great fame as a bell founder. Demand for his products even reached the United States of America.

1757–1814

Son of the founder, watchmaker and bell founder. The yard built by him in 1805 with its foundry (“Bregeme”) housed three generations of the Siedle founders.

1951

CEO and entrepreneur from 2000 to 2023 and since then the CEO of the holding and chair of the board of the family foundation. In a dynamic environment, shaped by globalisation, digitalisation and increased competition, Siedle is breaking new ground following the turn of the millennium. The businesses of tomorrow are all about networking, collaborations, software and service. Like the generations that came before her, Gabriele Siedle had to make the right changes at the right time to ensure the survival of this long-standing company.
