 | William Hyde Wollaston (1766-1828) was a giant figure in the history of platinum and palladium. |
| Wollaston made important discoveries in astronomy (the dark lines in the solar spectrum, a crucial tool in stellar astronomy today), biochemistry (he discovered cystine, the first amino acid), physiology (he was the first to postulate that human hearing is limited to certain frequencies), and physics (in atomic theory and crystallography). |
| The Wollaston Medal is named after him: the highest award granted by the Geological Society of London, first granted in 1832. |

| William Hyde Wollaston (August 6, 1766 – December 22, 1828) was an English chemist who is famous for discovering two chemical elements and for developing a way to process platinum ore. |
| He became wealthy by developing the first physico-chemical method for processing platinum ore in practical quantities, and in the process of testing the device he discovered the elements palladium in 1803 and rhodium in 1804. |
| His optical work was important as well, where he is remembered for his observations of dark Fraunhofer lines in the solar spectrum (1802) which eventually led to the discovery of the elements in the Sun. |
