Can someone please tell me a good site about famous mathematicians?

I have this research paper due for Algebra (what math teacher assigns research papers, right) about a bunch of famous mathematicians. I am having trouble finding information about them that is useful for my paper. In other words, not extremely detailed just the gist of their lives and their contributions. Please help me by suggesting as many links as you can. and please not wikipedia because my school doesn't let us use that site. Thanks so much!
