On 1 November 1929, Marie Curie spent her evening at the Plaza Hotel in New York. In her only public appearance in the city, she was scheduled as the guest of honor to address the third annual dinner of the American Society for the Control of Cancer. Feeling ill throughout most of her trip, she was able only to thank the audience of physicians. Robert G. Mead, a member of the society’s finance committee, read her speech, which was broadcast nationally on radio. Curie’s text focused on, as the New York Times put it, the “perils in radium” despite its use as a cancer treatment.
