I was interested in physics. I was a bit of a good brewer. I may have been instrumental in the early researches and discoveries that allowed the making of the light bulb later on. Some say that I established the physics of vacuums. I demonstrated experimentally a method of showing electrostatic repulsion. I discussed action at a distance. I benefited from a Grand Tour of France and England as part of my education. I was born on 20th November, the same day as Edwin Hubble, but in a different year.


Who am I?


P.S. On 20th November 1944. after 5 years of blackouts, the lights of London's Piccadilly Circus and Strand were switched on again.
