In July 1898, Curie and her husband published a joint paper announcing the existence of an element they named "polonium", in honour of her native Poland. On 26 December 1898, the Curies announced the existence of a second element, which they named "radium". In the course of their research, they also coined the word "radioactivity". via @Wikipedia
