- The first discovery of pitchblende in the United States was associated with gold ores at the Wood mine in Gilpin County.
- But an unexpected fact was noted: certain minerals (pitchblende, chalcolite, autunite) had a greater activity than might be expected on the basis of their uranium or thorium content. Marie Curie - Nobel Lecture
- Polonium was the first element to be discovered by Marie Curie and her husband Pierre as they analyzed pitchblende, an ore of uranium, in 1898.
- We found that pitchblende contains at least two radioactive materials, one of which, accompanying bismuth, has been given the name polonium, while the other, paired with barium, has been called radium.
