Who & When Platinum was discovered

Platinum was discovered by astronomers Antonio de Ulloa and Don Jorge Juan y Santacilia in 1735. However the first European reference to platinum appears in 1557 in the writings of the Italian humanist Julius Caesar Scaliger (1484-1558). Charles Wood independently isolated the element in 1741. The alchemical symbol for platinum was made by joining the symbols of silver and gold
