  4. I havetwoBirthdays H I S T O R Y • ‘Samarium’ was takenfrom a mineral, samarskite. • So in return, itcomesfromthelastname of a Russianmineofficial. There was a chemist, Paul Lecoq, and he was studyingdidymium, and hediscoveredthattwonewelementscould be foundindidymium (1853). Atthe same time, anotherchemist, Jean-charles, foundthatdidymiumcould be dividedintotwo parts (1879). Later, theynameditSamarium and Europium. Naming
