The Nussloch facility assumes production of the Histokinette, li (predecessor of the TP1020, li) from Cambridge Instruments, as well as production of the Knife Sharpener, re (SP9000) and the HI series (water bath and stretching table) from American Optical, including a technology transfer for cryostats.

The Leica Group is formed from the merger of the WILD LEITZ Group with the Cambridge Instruments Company (St. Gallen, Switzerland). The merger creates a new company that is the world leader in microscopes, surveying and photogrammetry systems, and scientific instruments. The name Leica was chosen for the new group because it represented the company’s best‑known brand. The name originated in 1924, when the world’s first 35 mm camera was developed and marketed by the Leitz company (LEItz CAmera).

Designs included the BIOCUT 2030, AUTOCUT 2040, SUPERCUT 2050; cryostat models FRIGOCUT 2800 N and FRIGOCUT 2800 E; the heavy and large section microtome P0LYCUT M and E; and POLYCUT MILL and HIST0MAT 3000 automatic plastic embedding machine.

New administration and training building 1984 opens in Nussloch.

The company was transferred to the U.S.‑based Warner‑Lambert Corporation. The companies Reichert (Vienna) and Jung (Nussloch) now supplied their products under the joint trademark “Reichert‑Jung”.

Associates begin to move‑in to the new Nussloch facility.

Company growth results in the Heidelberg facility reaching maximum capacity. A new facility in Nussloch is built which will eventually replace the Heidelberg factory.

Invention and delivery of a betting slip stamp and control device. Against great competition, R. Jung won the tender of the Staatliche Lotto‑ und Totogesellschaft in Stuttgart and then supplied 2,000 devices for installation at the Toto acceptance points in Baden‑Württemberg.

Introduction of new microtome models including the Model 1205 freezing microtome, invented by Gerhard Mößner, and, from the same inventor, the new Model 1120 serial section microtome, which replaced the old Minot microtome. This was later followed by the Model 1130, many thousands of which were shipped all over the world.

During the 2nd World War, measuring circuits were manufactured for installation in anti‑aircraft guns.

After the end of the 2nd World War, the budgets of universities and hospitals were modest, with little to no funds to support the purchase of new equipment. The company diversified its product lines in response, e.g., quick‑change punching dies and quick‑change cutting bushes, the manufacture of which was transferred to R. Jung from the SUSTAN standard program of the Hans Fickert company (Frankfurt/Main). Companies such as Daimler‑Benz AG, Volkswagenwerk, Ford and Opel used these punching standards for their punching tools in the production of sheet metal parts. Often up to 30,000 pieces of these tools left the automatic special department of the R. Jung company in one month. In the period 1950 - 1968 Gerhard Mößner was active as a representative of the R. Jung company in the German Standards Committee for punching tools

Introduced new microtomy offerings including the electric object cooling FRIGOMAT and the electric knife cooling FRIGOTOM. Both devices were later united in the electric cooling unit FRIGOMOBIL.

Further broadened the production range to include the production of drill bushings (as used in tool making for drilling jigs) and special tools and gauges for the telecommunications industry. The Bundespost (Federal Postal Service), Philips, Holland and Ericsson, Sweden became customers of the company, relationships which sustained over many years.

Microtomy innovation continues and expands.

• Microtome knives in production include the Thoma I model and the Thoma II model.
• Introduced the rocking microtome, the circular section microtome, the student microtome, the microtome Tetrander, the microtome K, the Minot microtome (a serial sectioning microtome), and the L1, L2 and L3 immersion microtomes (primarily used for brain sections in celloid embedding).

Product portfolio diversified to include spark plugs for heavy truck engines, cinema demonstration apparatus, Tankra gasoline gauges, primarily for installation in the luxury cars of Maybach and Horch, perimeters for measuring the visual field on the eye, rudder performance testers for racing boats, as well as Fish marking forceps to study the migration of fish in streams and rivers.

Published first edition of a Japanese‑language Jung microtome catalog, reflecting the region’s growing interest in Jung’s offerings. Japanese Emperor Hirohito, as a private scholar, had Jung microtomes in his biological laboratory. Exports became more and more extensive, and the number of agencies also grew steadily. For example, the Carl Zeiss company in Tokyo had been the Jung representative for Japan since 1920.

The company registered as R. JUNG Aktiengesellschaft, Fabrik für Präzisionsapparate.

Manufactured small munitions, as required by the government during war years.

The company converted to a limited liability company (GmbH) and retained this status until 1922, when Wilhelm Löw was entered as managing director in the commercial register at the Heidelberg district court.

The company moved to the new building at Hebelstrasse 45 in Heidelberg. For many years, however, the factory was without a connection to the city’s electricity grid. During this time, power was supplied via a stationary Deutz gas engine and via transmissions to the various floors.

Plans began to build a company factory just outside the city of Heidelberg, at the so‑called Baggerloch (“Excavation Hole”). This site was to accommodate the new main train station before World War I, but this was not to be realized until much later (1955).

Rudolf Jung’s brother‑in‑law Wilhelm Löw and Rudolf Jung’s sister Lisa Jung assume management of the company.

Rudolf Jung died on February 5, 1900 after a long illness.

Jung participates in the world exhibition in 1893 Chicago, Illinois (USA).

Jung moved to a larger office and factory premises at Landhausstraße 12 in Heidelberg.

Jung participates in the industrial 1888 exhibition in Brussels.

Rudolf’s brother‑in‑law Wilhelm Löw joins Jung. Löw was an ingenious inventor who developed many devices and included them in the delivery program and remained loyal to the company for 55 years (1878 — 1933).

The Jung company received several gold and silver medals of honor from the Palatinate Trade Association.

Published catalog markets a comprehensive product range in microtomy, and beyond. For example, the catalog included microscopes made by Leitz, Zeiss and Harnack.

Precision Engineering company R. Jung founded by Rudolf Jung in Heidelberg on October 1, 1872. The company bore his name until 1990. The first business premises were located at Hauptstrasse 15, where an ice cream parlor can be found today.

The young company focused on the production and marketing of the world’s first industrially mass‑produced microtome: the sled microtome. The sled microtome was developed in conjunction with Prof. Dr. Richard Thoma. Together, they realized the vision of a reproducible production of wafer‑thin histological kerosene sections for microscopic examination.

Rudolf Jung was born on February 20, 1845 in Calw/Northern Black Forest. There he entered the service of the Eye Clinic of the University of Heidelberg as an optician and precision mechanic. Though his work he developed a productive collaboration with Heidelberg pathologist Prof. Dr. Richard Thoma which would lead Jung to found a company and introduce first‑in‑class microtomes.
