Radium was discovered by Marie Sklodowska-Curie and her husband Pierre Curie on 21 December 1898, in a uraninite (pitchblende) sample. While studying the mineral earlier, the Curies removed uranium from it and found that the remaining material was still radioactive.
Marie's laboratory became the Mecca for radium research. Eva Ramstedt, who took a doctorate in physics in Uppsala in 1910, studied with Marie Curie in 1910-11 and was later associate professor in radiology at Stockholm University College in 1915-32.
