Despite many ‘authorities’ attributing the Lectron System’s invention to others (including to Dieter Rams), Georg Franz Greger, Dipl.-Ing, was the true and sole inventor and he proudly displays his creation for a publicity still taken on 1966-OCT-20.

Patented on 1965-MAY-08, the Lectron System was introduced by Egger-Bahn at the 1966 Spielwarenmesse (Toy Fair) held during that February. The Lectron System was hailed as a major achievement in teaching electronics.  Mr. Greger was awarded the prestigious Münchener Elektronik-Preis ‘First Prize’ at the Electronica show that same year.

The Lectron System was one of the leading exhibits at the 1967 Spielwarenmesse and numerous prominent Bavarian politicians stopped by the exhibit to receive a demonstration.
