Together with his wife, Marie Curie, he was awarded the Nobel Prize in physics in 1903: "in recognition of the extraordinary services they have rendered by their joint researches on the radiation phenomena discovered by Professor Henri Becquerel."
He died in a carriage accident in April 1906 after having his head crushed under the carriage wheel, thereby avoiding probable death by radiation poisoning, which later killed his wife.
