Discoveries and inventions like this don’t happen in a vacuum.
The operation of Michael Faraday’s original generator
was inefficient, but others quickly improved and varied the design.
André-Marie Ampère suggested that Pixii use a communtator
to convert his AC generator to a pulsed DC generator.
Faraday had a look at Woolrich’s generator
at Elkington Silver Electroplating Works in Birmingham
and “expressed his intense delight.”
James Clerk Maxwell mathematically formalized Faraday’s discoveries
and James Gordon worked under Maxwell’s supervision
at the Cavendish Laboratory.
