A Day in Birmingham.
whom I hadn't seen for about thirty years. She looked pretty much the same as she did all those years ago (except taller). Obviously we had a lot of catching up to do and only managed to get through a fraction in the four hours we were together. But it was fun...and I got to chat up a man who couldn't answer back (the best sort).
No idea who he was, and neither did the staff of the local museum across the square.
However they did manage to identify Priestley (discoverer of many different gases and fizzy drinks, who was chased out of his nearby residence, I believe, and ended up in the US)
and Watt, who invented lots of things but his main innovation was a very useful improvement to the steam engine.
Though I think they may have had clues.
Additional Note: A quick google search has revealed that my silent friend was one Thomas Attwood, British economist and political reformer. So it is strange he had so little to say for himself, really.
