Back in 1898, Marie Curie discovered radium in uranium ore. Having truly appreciated the discovery of his wife, Pierre Curie joined her. Having no laboratory, the spouses would jig tons of uranium ore in a shed and finally got radium in quantities sufficient for identifying its atomic weight. However, the discovered radium did not make the spouses rich, though the price of radium as a rare metal was sky-high. Yet, the husband and wife refused from obtaining a patent and commercial use of their discovery, as it was not in line with the spirit of science that required free exchange of knowledge. However, they were still awarded – with a Nobel Prize.
