Tore Lennart Frängsmyr was a Swedish historian. He was the first holder of the Hans Rausing professorship in the history of science at Uppsala university. Frängsmyr was born in 1938, the son of Johan and Linnea Karlsson. He grew up in Sjöbotten outside Bureå in Västerbotten, as the fifth of eight children; the family took the name Frängsmyr in 1954, after Frängsmyren, a wetland area near Sjöbotten. Tore Frängsmyr worked as a free-lancing journalist at the newspaper Norra Västerbotten in the 1950s, while he was still at school. After his secondary school graduation in Skellefteå, he moved to Uppsala in 1958, to study philosophy and history. He specialised in the history of science and the history of ideas, and finished his PhD at Uppsala university in 1969. The title of his dissertation was Geologi och skapelsetro. Frängsmyr wrote several works in English, including books about Linnaeus, Berzelius, and Vetenskapsakademien, which contributed to the spreading of knowledge about the Swedish history of science. He was also the chairman of the scientific board counselling the editors of Nationalencyklopedin when that encyclopedia was first being created. In 1981, he became Professor of the science of technology at Linköping University, and from 1982 he had a professorship in the history of science at Uppsala university. In 2001, the daughter of Swedish industrialist Hans Rausing donated money to Uppsala university to institute a chair in the history of science. Tore Frängsmyr became the first holder of this professorship, which he held until his retirement in 2007. He was an elected member of a number of learned societies, including the Royal Swedish Academies of Letters, History and Antiquities, the Sciences, and the Engineering Sciences. In Uppsala, he was Inspektor of the student organisationNorrlands nation from 2003 to 2011. Frängsmyr marriedBirgitta, née Thunholm, in 1970 and the couple had four children. They were married until his death in 2017.
