Klönne and Müller, 1876 - ca. 1921

The Klönne and Müller microscopical business operated in Berlin, Germany, for nearly 50 years. Between 1876 and approximately 1921, the firm produced microscope slides, microscopes, and related equipment (Figures 1-3). Until ca. 1887, they also published books. Slides by Klönne and Müller are not particularly common, and their microscopes are even less frequently seen. They produced a wide variety of specimens, many of which are still in very good condition (Figures 1 and 4).

Before the partnership formed, Julius Klönne operated a book publishing and retailing business. In 1876, Gustav Müller joined him, and the partners began to also sell microscopes, slides, and supplies. This implies that Müller possessed microscope-making skills, perhaps having recently left one of the high-quality manufacturers of Berlin. The business initially retailed slides that were prepared by H.C.J. Duncker - it is not known whether they continued to bring in slides from outside makers, or produced them in-house. Klönne died in 1880. A few years later, Müller sold the publishing/bookselling business while retaining the microscopy side. He maintained the name “Klönne und Müller” through at least 1921, the date of the last known reference to the company. Figures 6 onward trace Klönne’s and Müller’s businesses through advertisements and other publications, many of which illustrate the microscopes that they produced.

Little is known about the personal lives of Julius Klönne and Gustav Müller. The mixing of book publishing and selling with microscope manufacture is not an obvious combination. Perhaps they were relatives, merging business experiences for a common benefit? Noting that Klönne died 4 years after the partnership formed, when only 37 years old, he may have suffered from a chronic disease, in which case it is logical that a relative might have helped to take care of him. Speculation aside, Julius Klönne died on January 5, 1880 (Figure 5). His age at death indicates that he was born in 1844. The record also gives his birthplace as Wesel. Gustav Müller was clearly a skilled maker of microscopes in 1876, suggesting that he was then, at least, in his mid-twenties. The firm was listed in the 1921 Berlin telephone book, but not in later editions, suggesting that Müller retired shortly afterward and, considering his probable age, died a few years later.

Klönne and Müller operated from four addresses in Berlin, which can serve to date slides and other objects:

Prinzenstrasse 56, 1876 - 1880
Prinzenstrasse 69, 1880 - 1884
Prinzenstrasse 71, 1885 - 1887
Luisenstrasse 49, 1888 - 1921

 


Figure 1. Microscope slides from Klönne and Müller. The two on the left bear addresses, dating their production (Prinzenstrasse 71: 1885-1887, Prinzenstrasse 69: 1880-1884). The slides on the right, without addresses, appear to have been issued simultaneously with those on the left: Bracegirdle’s ‘Microscopical Mounts and Mounters’ includes such a slide, on which an owner wrote the date ‘1885’.

Figure 6. A brief history of the Klönne and Müller publishing business, from Gesammt-Verlags-Katalog des Deutschen Buchhandels, 1880. The firm was started on September, 1865, by C.A. Eduard Meyer. A partnership was formed with Julius Klönne in February, 1869, as Klönne and Meyer. In April, 1870, Klönne became the sole owner. He formed the partnership with Gustav Müller in April, 1876. Klönne had died by the time this was published, and Müller was the sole owner. He retained the business name ‘Klönne and Müller’ into the 1920s.

Figure 25. The book-selling segment of Klönne and Müller was acquired by Otto Berling ca. 1886. It was acquired by Gustav Vetter in 1888. This advertisement is from ‘Pharmazeutische Zentralhalle für Deutschland’, 1886.

 





Figure 26. A 4-page mini-catalogue was included in Richard Neuhauss’ 1887 ‘Anleitung zur Mikrophotographie für Aerzte, Botaniker, etc.’ The booklet was published by Klönne and Müller, indicating that Müller had not yet fully divested of the publishing arm. But, having sold the bookshop at Prinzenstrasse 69, the microscope maker had moved to an adjacent site at Prinzenstrasse 71.

 


Figure 27. An 1889 advertisement. It appeared in a catalogue of microscopy and bacteriology books that were published by Luisenstädttische Buchhandlung, their former business at Prinzenstrasse 69. Müller had moved the microscope business to Luisenstrasse 49. This was 4.5 km away from their former site, but adjacent to Charité Hospital, which would probably have been an ideal site to attract medical customers.

Figure 30. The last identified record of the Klönne and Müller business, their entry in the 1921 Berlin telephone directory. Assuming that Gustav Müller was in his mid-twenties when he formed the partnership in 1876, he would have been in his early 70s in 1921. Presumably, he retired around this time. It is also possible that another person(s) acquired the business from him at some earlier time point, then ended it ca. 1921.
