Based on what you read on the marie curie and the science of radioactivity website, name the scientists who shared the nobel prize in physics in 1903 and describe their contributions that were recognized by the award.

The award was divided to 3 pioneers of physics: Anotine Henri Bequerel, Pierre Curie and his wife Marie Curie. Bequerel was the first man to notice radioactivity since radioactive materials change the film of a camera. He noticed that uranium was radioactive. The Curie couple took his research one step further and examined many minerals and materials for radioactivity and with their work they managed to isolate new radioactive elements, radium and polonium.
