The Wikipedia is fantastic for questions like this.
http://en.wikipedia.org/wiki/Main_Page Marie and Pierre Curie discovered radium in 1898. Unfortunately the Wikipedia doesn't seem to have the history of calcium. However this site does: http://www.webelements.com/webelemen...m/history.html Apparently an Englishman named Sir Humphrey Davy first isolated calcium metal in 1808. |
