In 1920, he became a Foreign Member of the Royal Netherlands Academy of Arts and Sciences .  In 1922, he was awarded the 1921 Nobel Prize in Physics "for his services to Theoretical Physics, and especially for his discovery of the law of the photoelectric effect".  While the general theory of relativity was still considered somewhat controversial, the citation also does not treat the cited work as an explanation but merely as a discovery of the law , as the idea of photons was considered outlandish and did not receive universal acceptance until the 1924 derivation of the Planck spectrum by S. N. Bose . Einstein was elected a Foreign Member of the Royal Society (ForMemRS) in 1921 .  He also received the Copley Medal from the Royal Society in 1925. 
I was in [a] bar that evening, we had two or three beers, and I was one of the two sailors who are said to have disappeared mysteriously...The fight started when some of the sailors bragged about the secret equipment [radar, sonar, special screws, a new compass, etc.] and were told to keep their mouths shut. Two of us were minors....The waitresses scooted us out the back door as soon as trouble began and later denied knowing anything about us. We were leaving at two in the morning. The Eldridge had already left at 11 . Someone looking at the harbor that night might have noticed that the Eldridge wasn't there any more and it did appear in Norfolk. It was back in Philadelphia harbor the next morning, which seems like an impossible feat: if you look at the map you'll see that merchant ships would have taken two days to make the trip. They would have required pilots to go around the submarine nets, the mines and so on at the harbor entrances to the Atlantic. But the Navy used a special inland channel, the Chesapeake-Delaware Canal, that bypassed all that. We made the trip in about six hours" ( Vallee ).
