The Musée Curie (Madame Curie's Institute of Radium Museum) in Paris

Lest you think the Curies' discovery of radium and polonium back in 1898 was the end of Pierre and Marie's work on the topic of radiation and its role in fighting cancer and other medical issues (they had no idea they had also inadvertently opened up the Pandora's box of the modern age; they were devoted to working on radiotherapy), take a visit to the Curie Institute.

It is one of the planet's most prestigious institutions devoted to researching and treating cancer—not to mention awarding the biennial Curie Prize to EU scientists and laboratories that further the cause of fighting cancer.

But, on to the museum bit, where Marie Curie's laboratory has been preserved. This is not the shed a few blocks away where she and hubby Pierre first identified those radioactive elements (Nobel Prize #1).

But it is the lab where Marie worked on her research from 1914 (three years after Marie got Nobel Prize #2; Pierre had passed on in 1906, at which time Marie became the first woman ever to teach at La Sorbonne) until her death in 1934.

One year later at the lab, Marie's daughter Irène and Irène's husband Frédéric Joliot-Curie discovered artificial radiation—chalk up Nobel Prize #3 for the Curie clan.
