On April 20, 1902, Marie and Pierre Curie succeeded in isolating a chunk of the element radium, one of the earliest radioactive elements studied.
Pierre died in 1906, run over by a horse-drawn carriage. Marie won a second Nobel, in Chemistry, in 1911. Marie died in 1934 of aplastic anemia, a disease probably caused by her having received so much radiation over the course of her career.
