Surprisingly delightful read.<p>&quot;Einstein’s second wife, Elsa Löwenthal, recalls in her memoirs that a moment before he went on stage in Stockholm to receive the 1921 Nobel Prize in Physics, his by then very frail mother approached him holding a comb in her by then extremely arthritic hands. “There is nothing we can do about your head, Albert,” she said, kissing that head. “There is nothing I or anyone with the exception perhaps of God can do about your great big darling deformed head. But there is something we can do about your hair.”
