Italian inventor Bill Marconi established himself in Chelmsford to launch his trans-Atlantic wireless communications enterprise. The exhibits show the evolution of wireless radio signals broadcast from wide-spectrum spark generators, the signal being received by a cat’s whisker tickling a crystal. Subsequent exhibits show television, radar, and my god-parents’ enterprise, infrared engineering.
Marconi chose Chelmsford to launch his enterprise because it had a reliable supply of electricity and skilled technical workers already engaged in manufacturing electrical equipment.
