Joseph Priestley - Wikipedia
(I'm typing this just as the bells at the Church of England -Anglian- church across town have started chiming in hopes of luring more than the usual 20 or so older people to attend.)
About 4 miles from where I grew up is Birstall and in te market square I was used to seeing the big statue commemmorating Joseph Priestley as being the discoverer of oxygen.
I've never read much more than that about him until this morning chancing on his name and following links and OH MY! What an amazing guy he was!
If you want to feel as inferior as he made me feel and learn of all the religious dissent and riots in 1800s UK have a read of the wiki about him.
