Who is the greatest American? On June 5, the Discovery Channel will debut its TV show allowing us, the audience, to weigh in. Women nominated run from Madonna to Eleanor Roosevelt.

Discovery Channel's website has posted their list of nominees. Each has a short profile, so if any of these people are unfamiliar to you, you can read a bit about them. (Many are also profiled here on About.com as well -- use the search bar near the top of the page to search for those.)
