Today’s birthday May 15th 1859 : Paris born Pierre Curie; French physical chemist, cowinner with his wife Marie Curie of the Nobel Prize for Physics in 1903. The couple discovered radium and polonium in their investigation of radioactivity.
Here with his wife Marie and first daughter Irene.
Pierre Curie died in a street accident in Paris. It is likely that he would have eventually died of the effects of radiation, as did his wife, their daughter, Irène, and her husband, Frédéric Joliot, all exposed to huge doses of radioactivity during their experiments.
