TOP-SECRET-Ltr-to-Truman

The Oppenheimer-Einstein Letter

With the Best Picture at the Oscars this year going to Oppenheimer, I was reminded of this letter from Dr. J. Robert Oppenheimer and Professor Albert Einstein from June 1947 to President Truman. It seems like it never reached the President (as shown by some comments on page 6), but you can see the “TOP SECRET” stamp on it at the top.
