Strontium was officially called a new element in 1791, proved by studies from Thomas Charles Hope. At the same time as Hope, a German scientist named Martin Heinrich Klaproth was working on the same element. He had managed to create strontium oxide and strontium hydroxide. However, another scientist had found it a few years earlier in 1787. His name was Adair Crawford. It was found in a mine in the small town of Strontian, which is where it got its current name. The one who finally isolated strontium in 1808 was a chemist named Sir Humphry Davy.
