Discovery

It was originally discovered by the clergyman Rev. William Gregor (Cornwall, England) in the mineral ilmenite (FeTiO ₃) in 1791. He called this iron titanite menachanite and the element menachin, for the Menachan parish where it was found. It was rediscovered in 1795 by the chemist Martin Heinrich Klaproth (Berlin, Germany), who called it titanium because it had no characteristic properties to use as a name. Titanium metal was first isolated by the Swedish chemists Sven Otto Pettersson and Lars Fredrik Nilson.

Name Derived From

The name derives from the Latin titans, who were the mythological "first sons of the earth".
