I need a very detailed website about FDR.

My Topic is Choose someone who you belive to be a great leader in US history and describe reasons why this person was such an influential leader.

All the links I'm coming up with say the same thing so if you guys could help me in finding something more elaborate and topic appropriate, that'd be awesome.

Thanks!

I found this written by the FDR library site. If this isn't good enough, please tell us what you are looking for.
