In his autobiography, Richard Feynman mentioned William Laurence standing next to him during the Trinity test. Feynman stated, "I had been the one who was supposed to have taken him around. Then it was found that it was too technical for him, and so later H.D. Smyth came and I showed him around." Nuclear historian Alex Wellerstein has called Laurence "part huckster, part journalist, all wild card ... improbable in every way, a real-life character with more strangeness than would seem tolerable in pure fiction."
