As a child, young Albert was once struck ill, and to keep him entertained while he was bedridden, his father gave him a compass. It fascinated him and was said to be the first scientific thing he studied, as he immediately knew that some kind of invisible force caused the compass to point north.
Einstein absolutely despised socks and went without wearing them as often as possible. He saw them as pointless and inefficient, as they often ended up with holes, and he felt that shoes alone did the job of protecting one's feet. He once wrote to his second wife about how he "got away without wearing socks" while at Oxford.
