Titanium ore was first discovered in 1791 in Cornish beach sands by an English clergyman, William Gregor. The actual identification of the oxide was made a few years later by a German chemist, M.H. Klaproth. Klaproth gave the metal constituent of this oxide the name titanium, after the Titans, the giants of Greek mythology.
