when was titanium discovered

Titanium was discovered in 1791 by Reverend William Gregor, an amateur mineralogist and clergyman in Cornwall, England. He found titanium in the form of a white metal oxide in black sand near Manaccan and initially called it manaccanite. Later in 1795, the element was independently rediscovered by German chemist Martin Heinrich Klaproth, who named it titanium after the Titans of Greek mythology. The metal was first isolated in its pure form in 1910 by Matthew A. Hunter. Thus, the original discovery date of the element titanium is 1791.
