Well said. Tommy Flowers’ story is fascinating.
Another interesting Tommy is the American Thomas Midgley whose efforts were less beneficial. He came up with the idea for both CFCs and adding lead to petrol.
In later life he suffered from polio and invented a pulley system to help him move in bed. He got entangled in it and it strangled him.

Horrible way to go but considering the damage he likely did to the planet it seems strangely apt that he met his end due to one if his own inventions.
