Dr. Hugh Everett III, phD was what Scientific American magazine calls "one of the most important scientists of the 20th century." A quantum physicist who authored "Everett's Many Worlds Theory" in the 1950's, Everett inspired countless science fiction books, movies and Star Trek episodes with the concept of parallel universes. As a young teenager he traded letters with Albert Einstein, debating whether it was something random or unifying that held the universe together.
