May 21, 1954 Dear Professor Einstein: It may be that I said more than I was aright to say when yesterday evening I expressed myself that Einstein is humanly obliged not to be indifferent to the wrong that was and is still done by an organized group of scientists. But because of your position of a recognized leader among scientists and fighter for human rights, I feel obligated to you not to keep you uninformed. These are two problems, entirely independent: Am I right in my theory? I am striving to prove it. Have I the right to express in writing the conclusions to which I came in an honest endeavor? Though the answer is elementary, this right was so mistreated that, following an attack this month, after some hesitation, I decided to ask more than just a few minutes of your most precious time. With sincere regard, Immanuel Velikovsky
