Alexander Graham Bell (March 3, 1847 – August 2, 1922)
Thomas Alva Edison (February 11, 1847 – October 18, 1931)
Henry Ford (July 30, 1863 – April 7, 1947)
Steven Jobs (February 24, 1955 – October 5, 2011)

These people radically changed the lives of every American alive in their lifetime. It was awesome for me.
