There are some people whose 15 minutes will never be up. They are beyond well-known, more than famous. They are legends. Their mark on our consciousness is permanent. Albert Einstein will still be revered 100 years from now; Marilyn Monroe will still exemplify vulnerability; Adolf Hitler will still embody the unspeakable. These people are mythic. We all recognize their names and we all can tell their stories. And since the lives of the legendary tend to intertwine, they have often commented on one another. We've gathered those observations as well, to combine the photographs of our immortals with the most enlightening of remarks about them.
