This is simply amazing. ♥
Richard Feynman’s first wife, his high school sweetheart Arline Greenbaum, died of a rare form of tuberculosis at age 25. He was crazy in love with her, and, when she was near death, he rushed from Los Alamos, where he was working on the Manhattan Project, to be by her side at the Albuquerque sanatorium. She died on on June 16, 1945. You can get a fuller account of their romance and her death at the Big Think and Brainpickings, both of which reproduce Feynman’s letter to the departed Arline.
