From now until the end of October, there is a special exhibition hosted by the Centre for Art and Media Technology in Karlsruhe on the work and lasting influence of author, tinkerer and entrepreneur Hugo Gernsback. The namesake of the Hugo literary prize for science-fiction was born in Luxembourg and received training in a German military signals unit in Bingen, establishing his enduring interest in ham radio and helping to grown the network of amateur and hobby radio operators world-wide, before immigrating to America. Settling there, Gernsback entered into the publishing industry, first distributing a catalog-magazine hybrid for wireless accessories and several other popular mechanics-type publications following his interests in emerging technologies and feeding his sense for speculation.
