Richard Feynman was one of the best-known and most influential physicists of his generation. In the 1940s, he played a part in the development of the atomic bomb; in 1986, as a key member of the Rogers Commission, he investigated the Space Shuttle Challenger disaster and identified its cause; in 1965, he and two colleagues were awarded the Nobel Prize “for their fundamental work in quantum electrodynamics, with deep-ploughing consequences for the physics of elementary particles.” He was also an incredibly likeable character, and made countless other advances in his field, the complexities of which I will never be able understand.
In June of 1945, his wife and high-school sweetheart, Arline, passed away after succumbing to tuberculosis. She was 25-years-old. 16 months later, in October of 1946, Richard wrote his late wife a heartbreaking love letter and sealed it in an envelope. It remained unopened until after his death in 1988.

October 17, 1946
I adore you, sweetheart.
I know how much you like to hear that — but I don't only write it because you like it — I write it because it makes me warm all over inside to write it to you.
It is such a terribly long time since I last wrote to you — almost two years but I know you'll excuse me because you understand how I am, stubborn and realistic; and I thought there was no sense to writing.
But now I know my darling wife that it is right to do what I have delayed in doing, and that I have done so much in the past. I want to tell you I love you. I want to love you. I always will love you.
I find it hard to understand in my mind what it means to love you after you are dead — but I still want to comfort and take care of you — and I want you to love me and care for me. I want to have problems to discuss with you — I want to do little projects with you. I never thought until just now that we can do that. What should we do. We started to learn to make clothes together — or learn Chinese — or getting a movie projector. Can't I do something now? No. I am alone without you and you were the "idea-woman" and general instigator of all our wild adventures.
When you were sick you worried because you could not give me something that you wanted to and thought I needed. You needn’t have worried. Just as I told you then there was no real need because I loved you in so many ways so much. And now it is clearly even more true — you can give me nothing now yet I love you so that you stand in my way of loving anyone else — but I want you to stand there. You, dead, are so much better than anyone else alive.
I know you will assure me that I am foolish and that you want me to have full happiness and don't want to be in my way. I'll bet you are surprised that I don't even have a girlfriend (except you, sweetheart) after two years. But you can't help it, darling, nor can I — I don't understand it, for I have met many girls and very nice ones and I don't want to remain alone — but in two or three meetings they all seem ashes. You only are left to me. You are real.
My darling wife, I do adore you.
I love my wife. My wife is dead.
