The Entrepreneur Ernst Leitz I
Carl Kellner , mechanic and self-taught mathematician, published his treatise Das orthoskopische Ocular, eine neu erfundene achromatische Linsencombination The orthoscopic ocular, a newly invented achromatic lens combination in , describing a new optical formula he had developed. The ocular was capable of rendering an image with the correct perspective, free of the distortions typical of other microscopes at that time. Following his early death on 13 May , his widow continued the business he had left behind, the “Optisches Institut” optical institute.
The fine mechanic Ernst Leitz I. He was trained as an instrument maker for physical and chemical apparatus and had several years’ experience making watches in Switzerland. Initially, Leitz was a part shareholder of the business in , but took over as sole owner in and continued it under his own name.

This page is linked from my Geological Microscopes website. Up to ten years or so ago, I knew very little about Leitz microscopes. Although they are widely used in academia, very few happened to be in the geology labs where I worked. They were not particularly good looking to my eyes, and with this prejudice I thought I would not like to actually own or use one, especially the older black enamel models.
What a mistake! In fact, Leitz microscopes are extremely well designed and constructed, including superior optics, and after you have one, you will regard it as a very satisfying and handsome instrument. There is no substitute for quality, and Leitz was at the peak. After owning and renovating more than 30 Leitz microscopes as part of my hobby, I know this for a fact.
Information about Leitz microscopes is rather scattered and not always easy to find, so as more photos and links come my way, I will post them here. Because of my background in geology, a lot of the ones I know are polarizing or petrographic versions, but all types will be included. A very fine article about black enamel Leitz scopes made between the late 30s and early 70s has been written by Gregor Overney and Normand Overney, and published in Micscape magazine March

The historical microscope collection housed in the Moody Medical Library is considered one of the major collections of its type owned by an academic institution in the United States. The collection consists of representative samples documenting the development of microscopy from the 18th through the first quarter of the 20th century. The work of more than 30 individual makers or firms is included. The microscope collection dates from , when the Library acquired 33 microscopes from Dr.
John Bunyan with a grant from the Moody Foundation of Galveston. Bunyan provided additional instruments as well as partial cataloging for the collection in subsequent years. Of the 82 instruments, 60 percent are associated with him. The remaining consists of microscopes from the Departments of Anatomy and Pathology, gifts from former faculty and friends of the University, and a purchase of replica microscopes.
