July 5, 1795 – Death of Antonio de Ulloa y de la Torre-Giralt, discoverer of platinum

Spanish scientist, soldier, and sailor who, during a trip to Ecuador, discovered a new mineral in the gold mines of the Pinto River in Peru, which he called "Platina de Pinto" because of its resemblance to silver and for having found it in that river. However, he eventually stuck with the platinum name. Antonio de Ulloa was the first to carry out a rigorous analysis and description of this element with atomic number 78 on the periodic table.

Back in Spain he was captured by the English and taken to England. He took advantage of his stay there to complete his knowledge and publish some studies on the new mineral.

Meanwhile, in 1741, Charles Wood brought the first samples of platinum to England and, following Ulloa's publication in 1748, they began to study the properties of this highly valuable element in England and Sweden. Because of this fact, British historians say that platinum was discovered by Wood and not by Antonio de Ulloa.
