Greatest and most Influential Thinkers

[KingNothing]

In your opinion, what are the greatest and/or most influential thinkers in the sciences of all-time?

You may include sciences other that Physics if you so choose. I know this is very open ended, so you might want to make a top 5.

I would say that Richard Feynman was quite an influential thinker...

Einstein, Maxwell, Mendel, Lister, Copernicus, Darwin, Newton, in no particular order are the names that pop into my mind. They are not necessarily the most brilliant minds in their respective fields, but they introduced important, radical new theories.
