He is best known for his discovery of the chemical elements holmium and thulium. Cleve earned his BSc and PhD from Uppsala University in 1863 and 1868, respectively. After receiving his PhD, he became an assistant professor of chemistry at the university. He later became professor of general and agricultural chemistry. In 1874, he theorised that didymium was in fact two elements; this theory was confirmed in 1885 when Carl Auer von Welsbach discovered neodymium and praseodymium.\r\n\r\nIn 1879 Cleve discovered holmium and thulium. His other contributions to chemistry include the discovery of aminonaphthalenesulfonic acids, also known as Cleve's acids. From 1890 on he focused on biological studies. He developed a method of determining the age and order of late glacial and postglacial deposits from the types of diatom fossils in the deposits, and wrote a seminal text in the field of oceanography.","2025-08-11 12:14:33",[],[],[],[],[61],{"id":62,"txt":63,"latitude":64,"longitude":65,"country":66},3184,"Bastnäs Mines, Riddarhyttan, Skinnskatteberg, Västmanland County, Sweden",59.8467628,15.5896211,"Sweden",5,[69],{"id":70,"year":71,"html":72,"doi":73},128267,2003,"Holtstam, Dan, Norrestam, Rolf, Andersson, Ulf B.
