The Braun Lectron system consists in an extensive range of magnetic modules that can be freely organised on a conductive plate to form a variety of functional circuits.The system was designed by Georg Franz Gregor and initially marketed in 1966 by the Egger-Bahn Company. Following the collapse of Egger-Bahn, the Braun Company acquired the sales rights to the design in 1967, maintaining them until 1972. 

Erwin Braun’s interest in the product was as a pedagogic instrument, rather than a toy as it had previously been marketed through Egger-Bahn. This re-orientation of the product was consistent with the Company’s general belief in industrial design as a social good. When Gillette acquired the Braun Company it instituted wide-ranging economic rationalisations – thinning out and stopping a great number of lines, including, in 1972, the Lectron System.

The Braun Company made three  additions to the system: radio and intercom construction sets, designed by Rams and Greubel, and the Book Laboratory on this page.  The last was illustrated by the widely published cartoonist, Jules Stauber. In 1970 the design was awarded the prize for 'the most beautifully illustrated book for young people' at the Frankfurt book fair.
