history

LD Didactic GmbH emerged from the spin-off of the teaching materials division of Leybold GmbH . This was founded in 1850 and was already producing teaching aids in the 19th century before the production of vacuum pumps was set up in 1906 .

From 1987 Degussa AG was the sole owner of Leybold AG. In 1994 the company sold the vacuum pump production to the Swiss Oerlikon-Bührle Group , with the teaching material division initially remaining with Degussa. In 2000, the teaching materials division was sold as Leybold Didactic GmbH to private investors around Joachim Moser, who also became managing director. The company name was later changed to LD Didactic GmbH.

In 2007 the company with 180 employees went bankrupt, which ended in early 2009 with the acquisition by Aurelius . In the 2008 financial year, sales of EUR 40 million were achieved. As a result, two more companies in the field of technical teaching materials were taken over: In 2011, Dr. Luhs and in 2012 the British Feedback Group (sales around EUR 7 million).

In 2013, LD-Didactic, as an Aurelius subsidiary, acquired the technology product portfolio from ELWE and the rights to the ELWE Technik brand in the field of electrical training and further education. ELWE training systems have been produced in Hürth since then.

LD Didactic is headquartered in Hürth near Cologne, has two production sites in Germany (Hürth and Urbach) and, since 2016, a production facility with increasing importance in Hungary (company LD Operations Kft. In the town of Cegléd ). LD Didactic also operates two local sales offices for Latin America and Great Britain.

LD Didactic sells its products in more than 80 countries.

Products

The LD produces and sells teaching materials for science and technology lessons. Traditionally, the focus was and is on physics experiments for school lessons.

The CASSY system, which consists of various interfaces and attachable sensors, is offered for the computer-aided acquisition and evaluation of measurement data. The CASSY system was introduced in 1990 and all new devices have been downward compatible since then. CASSY is an acronym and stands for Computer Assisted Science SYstem . The CASSY system competes with Cobra from Phywe or measured value acquisition with sensors from Vernier or Pasco.

Simulog (from simulator and logic ) is the name for a teaching system for teaching purposes fromthe company LD Didactic GmbH, with which elementary logic circuits can be set up using a simple plug-in system.
