The Best Choice

Other good candidates that compete withe Eleanor is;
Clara Barton: Founder of the Red Cross.
Jackie Robinson: Broke the baseball color line.
But I believe Eleanor Roosevelt is the best candidate; Unlike Clara, Eleanor got into many other groups, instead of just focusing on one. While Jackie did break the baseball color line, that was only in baseball, not in other sports or the whole country, while Eleanor was helping out to break the color barrier in everything.
