Björn Olof Lennartson Kurtén (1924 – 1988) was a distinguished vertebrate paleontologist. He belonged to the Swedish-speaking minority in Finland. He was a professor in paleontology at the University of Helsinki from 1972 up to his death in 1988. He also spent a year as lecturing guest professor at Harvard University in 1971
He was also the author of an acclaimed series of books about modern man's encounter with Neanderthals, such as Dance of the Tiger (1978, 1980). When asked what genre these works belonged in, Kurtén coined the term paleofiction to describe his oeuvre. This genre was popularized by Jean M. Auel in her Earth's Children series of books. He received several awards for his books around popularized science, among others the Kalinga Prize from UNESCO.
In the 1980s, Kurtén also hosted a 6-part TV series about the ice age, co-produced by several Scandinavian TV channels.
Kurtén also published some fifty scientific works, two of them in cooperation with the Spanish paleontologist Miquel Crusafont Pairó.
