Here is a transcribed article from the September 1967 issue of Electronics Illustrated describing what is, in fact, the BRAUN Lectron educational toy designed by Dieter Rams and Jurgen Greubel. Interestingly, the toy's U.S. marketing, at the time, seems to have been pretty thoroughly scrubbed of conspicuously German names. The article mentions that the system was "imported from Germany," but neither Braun's, Rams's, nor Greubel's name is given, and U.S. distributor Raytheon gets most of the credit.
