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:

Apparently an Englishman named Sir Humphrey Davy first isolated calcium metal in 1808.
