Discovery of Strontium
In 1790, along with his colleague William Cruickshank at the Royal Military Academy, Woolwich, London, Crawford noted the distinctiveness of strontianite from barium minerals, and may thereby be said to be the discoverer of strontium. However, it could also be claimed that the honour should go to Humphry Davy who, in 1808, became the first to isolate the pure element.
