History

(Ger. Weisse Masse, white mass; later Wisuth and Bisemutum) In early times bismuth wasconfused with tin and lead. Claude Geoffroy the Younger showed it to be distinct from leadin 1753.


Sources

Science Quote

'To myself I seem to have been only like a boy playing on the seashore, and diverting myself in now and then finding a smoother pebble or a prettier shell than ordinary, whilst the great ocean of truth lay all undiscovered before me.'

Isaac Newton
(1643-1727)
