History of the Paul Waechter microscopes
Paul Waechter (1846-1893) was trained as an optician and mechanical engineer at the famous Zeiss optical workshop in Jena, Germany. In 1872, Waechter established his own optical workshop at Köpnicker Strasse No. 115 in Berlin. In 1886, Waechter published advertisements for his microscopes in scientific journals with the mention 'Student of Dr. Zeiss.' His earlier instruments were signed in ornate letters on the tube with 'Paul Waechter in Berlin' or, more simply, 'Paul Waechter, Berlin.' Around 1890, the demand for his microscopes had increased so much that he moved his workshop to a larger premises in Friedenau, Berlin, initially at Albe Strasse 21 and later at Nied Strasse 19. The company remained based in Friedenau into the early 20th century. During that time, the company was called 'Optical Workshop Paul Waechter,' although Waechter passed away around 1893.
Between 1872 and 1892, Waechter produced more than 20,000 microscopes, mainly for research into trichinae in meat. It was the famous scientist Rudolf Virchow (1821-1902) who around 1870 succeeded in persuading various German states to make testing pork for trichinosis in slaughterhouses mandatory. Waechter and several other German microscope manufacturers designed and produced microscopes specifically to meet this need. Many of these instruments were exported to countries outside Europe, including the US. An advertisement seen here comes from the German magazine 'Zeitschrift für Wissenschaftliche Mikroskopie und Mikroskopische Technik', which is available online. In the mid-1930s, the company was taken over by the Pridat family and the optical workshop moved from Berlin to Potsdam in present-day Poland (formerly the German state of Prussia).
