Richard Feynman dies at the UCLA Medical Center due to complications from cancer (liposarcoma) and a ruptured duodenal ulcer, leading to kidney failure. He declined dialysis, and his wife Gweneth, sister Joan, and cousin Frances Lewine were by his side during his final days. His death marked the end of a highly influential career in theoretical physics and science popularization.

Richard Feynman marries Gweneth Howarth at the Huntington Hotel in Pasadena. Gweneth, originally from England, was working as an au pair when they met. This marriage proved to be a long-lasting and supportive partnership.
