There are so many people that are influental or have been during this century. Bad or good, the list can go on ans on. Luke thinks that Franklin D. Roosevelt was the most influential person of the 1900's. Roosevelt was diagnosed with poloio and was still successful politically. He helped America reach out of a finicial crisis bigger than the one we have today, and also to succeed in the the war. As I said, so many people have made a diffrence, and have been influential, Roosevelt helped complete a task that we need to complete today also. Many of you can relate to this. Great Question.
