Famous Chemist

[potterfan3]

21:24 on Tue 16/May/06 My chemistry teacher has had a heart attack (he's fine), and my physics teacher is also been away for a while (she's in hospital). Anyway, our new physics teacher is a spitting image of einstein, so we are beating round the brush for a famous chemist for our new chemistry to look like, however we do not know any famous chemists (real famous huh?). Can you give me a name and picture of a famous chemist, and maybe what they did.

Thanks
