Despite many ‘authorities’ attributing the Lectron System’s invention to others, Georg Franz Greger, Dipl.-Ing, was the true 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.

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.
