history

Episcope by Eduard Liesegang, around 1926

Friedrich Wilhelm (FW) Eduard Liesegang (1803–1871) was the founder of the Ed. Liesegang oHG , which became known for its projectors .

In 1854 Eduard Liesegang took over a photo business and founded the company. His son Paul Liesegang (1838–1896) published a standard work on photography in 1856 , founded the magazine Das Fotografische Archiv in 1860, and in 1877 submitted the first Liesegang patent . At the end of the 19th century, a grandson of the founder and later co-owner of the company, the chemist Raphael Liesegang , developed ideas for "electrical television " and the forerunners of the videophone . At that time the company owned a photographic factory in Elberfeld . In 1873 the company moved to Düsseldorf , where it settled on Kavalleriestraße.

When Paul Liesegang died in 1896, his son Raphael Liesegang and two of his brothers took over the factory, which they modernized. The photo paper and developer department was sold to the Friedrich Bayer & Co. paint factory in Leverkusen in 1907 . This would later become the nucleus of the Agfa works. When Raphael Liesegang left the company, the optical department was continued by his brothers in Düsseldorf. Shortly after the turn of the century, optics and projection technology had established themselves as the company's focus. In 1926 the company moved to an area in Düsseldorf-Unterbilk . The site of the Alte Liesegang factory , Volmerswerther Straße 21, where slide projectors were previously produced, has now become a center for artists and designers.

After the insolvency of the former family-owned Liesegang oHG in 2004, the company was re-established in 2006 as Liesegang Technology Vertriebsgesellschaft mbH , based in Essen. Around 50 employees achieve an annual turnover of around 30 million euros. Today the company is a department of TAS-media.com GmbH in Bochum.
