Titanium was first discovered in 1791 by English clergyman/chemist William Gregor. He found it in a type of black sand that is now known as ilmenite. A German chemist named Klaproth discovered the element in an ore called rutile. He named the element after the Titans, the sons of the Earth.
There was not a commercially viable process for
separating Titanium from ores until Wilhelm Kroll designed one in 1937.
