Even before the establishment of 2 German states, the thermometer factory "M.K. Juchheim" was established in Fulda and already exhibited at the Hannover Messe in 1949. Konrad Adenauer became Federal Chancellor. In the years of the economic miracle the Fulda-based company also flourished. By 1952 it had grown from 6 to 100 employees and by 1970 this number had increased tenfold. The production area increased from 350 to 12,000 m².

In 1966 the production of platinum glass sensors began. Measuring and control devices on an electronic basis were added to the product range. While the world mourned the breakup of the Beatles, Moritz Juchheim founded the first subsidiary in Belgium in 1971. This was the step that began internationalization. In 1978, JUMO was the first company to use processors in control technology.

While Erno Rubik's "Magic Cube" rose to cult status, JUMO continued to develop its range of services and, for the first time, offered these for metal processing and electronic modules to external customers as well. The field of liquid analysis was also expanded.

In 1985 Germany cheered for the 17-year-old tennis phenomenon Boris Becker. In the same year Peter Juchheim, eldest son of company founder Moritz and Managing Manager alongside his father since 1965, died in 1985. His younger brother and current General Partner Dipl.-Ing. Bernhard Juchheim took his place. In 1989 when the Berlin Wall fell, JUMO achieved a breakthrough: robots were used for the first time in temperature probing.

The federal government moved from Bonn to the old and new capital Berlin. JUMO's development department relocated to a new building. Over the years, this department has produced high-tech devices, process control systems, smart transmitters, bus technology, and state-of-the-art visualization software. As a result, the JUMO mTRON automation system was launched on the market in 1997.

After the founding of the JUMO training center in 1995, the Juchheim family suffered another loss: in 1996, company founder Moritz Juchheim passed away.

The new millennium did not begin with a crash, but rather with a record for JUMO: the company achieved sales of over 100 million euro for the first time. In 2002, when the European currency was also introduced as cash, JUMO inaugurated the new sales and production building for the temperature sensor technology product line in the Eisweiher industrial park. The building had a total area of 4,680 m².

In 2003, the brand name JUMO became the company name and Michael Juchheim became Managing Director alongside his father Bernhard. JUMO grew on the Asian and Eastern European markets. It could tap new target groups with complete automation systems.

JUMO is growing constantly and now employs more than 2,500 people worldwide. Certification of the DKD laboratory by the Deutsche Akkreditierungsstelle GmbH (DAkkS) opened the door to new services. The new incoming goods logistics center opened in 2012 and a 100,000 m² site was acquired in 2013 for a new sensor manufacturing plant.

In 2016, JUMO made its only acquisition of an external company to date by taking over PGT Thermprozesstechnik GmbH. The company specializes in the production of innovative plastic temperature probes and had been a JUMO system partner for many years beforehand. JUMO received several awards for above-average growth and for being an exemplary employer.

In 2020, Dimitrios Charisiadis was appointed as the third Chief Executive Officer. He took over the "Sales, Development, and Production" areas. Bernhard Juchheim was responsible for "Human Resources" and Michael Juchheim for "IT and Finance".

As of 2022, Bernhard Juchheim and Michael Juchheim have been focusing on their shareholder role in the family company and have stepped back from operational management. In addition to Dimitrios Charisiadis, Steffen Hoßfeld has been appointed as the new Chief Executive Officer.

2023: JUMO celebrates its 75th anniversary!

Only 4 percent of all companies in Germany are over 70 years old. 75 years of JUMO was therefore a more than worthy occasion to celebrate the history of an extraordinary company. From the very beginning, it was clear that the employees would be the focus of the anniversary year. After all, they have made JUMO what it is today: a globally active, successful medium-sized company and "hidden champion" that has never lost sight of its roots as a family business. True to the anniversary motto, the anniversary project team kept JUMO employees "on the go" for 12 months with numerous events and activities, providing many unforgettable moments.
