Hi Gents, John Henry Holmes, a Newcastle Electrical Engineer and inventor of the quick break switch.
Mainly from the days of DC and "key type" switches, where it was possible to partly open the switch, leaving it arcing and dimming the lamp. Very much like the gas lighting. BUT not a good thing as the switches were often on wooden bases!!!
Discovery museum in Newcastle has an exhibition of his designs.
