Martin Heinrich Klaproth (1743-1817). William Gregor (1761-1817), a minister who also dabbled in experiments, discovered a type of sand in 1791 from which a mysterious white powder could be produced. Klaproth recognized the yet-unknown element, and Henri Moissan (1852-1907) prepared pure titanium by electrolysis. 

Titanium (Ti, [Ar]3 d24s2), name and symbol from the Titans of the Greek mythology. Discovered (1791) by the British Rev. William Gregor. 

Titanium - the atomic number is 22 and the chemical symbol is Ti. The name derives from the Latin titans, who were the mythological first sons of the earth . It was originally discovered by the English clergyman William Gregor in the mineral ilmenite (FeTiOj) in 1791. He called this iron titanite menachanite for the Menachan parish where it was found and the element menachin. It was rediscovered in 1795 by the German chemist Martin Heinrich Klaproth, 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.

Titanium was discovered in 1790 by Engfish chemist William Gregor. Five years later in 1795, Klaproth confirmed Gregor s findings from his independent investigation and named the element titanium after the Latin name Titans, the mythical first sons of the Earth. The metal was prepared in impure form first by Nilson and Pettersson in 1887. Hunter, in 1910, prepared the metal in pure form by reducing titanium tetrachloride with sodium.

After titanium was discovered in 1791 by the Reverend William Gregor in Cornwall, its atomic weight was determined by such able chemists as H. Rose, C. G. Mosander, and J.-B.-A. Dumas, but the results showed such great discrepancies that Mendeleev predicted that another element would be found in titanium ores (17).

Titanium was discovered in 1791 by William Gregor, an English clergyman and amateur chemist. He identified it in a black sand (now known to be ilmenite) sent to him for analysis from the Menacchan Valley in Cornwall. Four years later, the famous German chemist Klaproth rediscovered the element in the ore rutile, one form of titanium dioxide. He gave it the name titanium after the Titans who in Greek mythology were the sons of Earth.

Titanium was discovered by English clergyman William Gregor (1761-1817). Gregor studied minerals as a hobby. He did not think of himself as a chemist, and yet his research led to the discovery of titanium. 

English clergyman William Gregor discovers an oxide of titanium. German chemist Martin Klaproth makes a similar discovery four years later. The element is not isolated until 1910. 

Titanium was discovered by the Reverend William Gregor in 1791, and is named after the Titans of Greek mythology.

The main compounds are titanium(IV) salts and complexes titanium(II) and tita-nium(III) compounds are also known. The element was first discovered by William Gregor (i76i-i8i7) in 1789.
