Personally he is simple, direct, unaffected and rather winning. His enormous intellectual energy, his clear vision and sense of physical reality, and his enthusiasm strike the most casual observer. He is aware of his great position, but not in the least conceited. He does not expect relativity in its present form to last many decades, and hopes that further work will soon go beyond it.
A good example of how received opinions can effect our assessments of people. Had Einstein been an important but un-famous scientist, no one would ever write shmaltz like that about him on a casual meeting.
