Throwback 1986 – R. & S. KELLER GmbH Foundation

Did you know that KELLER didn’t start out as a software company, but as a publishing house?

Under the publisher’s name “R. Keller”, Mrs. Keller first published educational booklets on the topics of CNC machine tools, geometric and technological as well as mathematical basics in 1982. Our SYMplus™ workbooks are still a reminder of this time.

The success of the products finally led to the founding of R. & S. KELLER GmbH by Mr. and Mrs. Keller in 1986. This photo shows the festivities to celebrate the founding of the company.
