The Greatest Minds of All Time

List of the Greatest Minds of All Time, throughout history. This list represents the most influential thinkers across various disciplines, ranked in a way that represents the power of their ideas and their impact on the world. The wisest men and women include top philosophers, physicists, famous poets, thinkers, teachers, physiologists, artists, inventors, engineers, the most irreplaceable CEOs in the world, economists and politicians and those whose talents span across many fields of study.

This list takes a historic perspective, so the greatest thinkers who are included on this list come from many different eras. The greatest minds of the 21st century may be quite different from great geniuses from the distant past, but each person should be judged within the context of the time that they were living. For example, inventing a new type of telephone in 2013 would not qualify one as "the most brilliant mind of all time," but in 1876 when Alexander Graham Bell first patented the telephone, it was an act of genius not seen before.
