Sir John Ambrose Fleming – Born in Lancaster on 29 November 1849

Another famous person born on the 29th of November was the physicist, inventor and electrical engineer, Sir John Ambrose Fleming.

Born in Lancaster in 1849, Ambrose Fleming was famous for inventing the first thermionic valve (aka diode) in 1904.

Hmm, ever curious, we looked up thermionic valve, and discovered that it is a gadget that controls the flow of electricity through a vacuum inside a sealed container.

That’s the great thing about visiting the British Newspaper Archive – you learn something new every day!
