Morten Thrane Esmark
Morten Thrane Esmark was born in Kongsberg in Buskerud, Norway as a son of Professor Jens Esmark, a professor of mineralogy. His given name came from his maternal grandfather Danish zoologist and mineralogist, Morten Thrane Brünnich. Esmark took his theological exam in 1825 and first began his ministry as chaplain in Eidanger, in Tromsø, Troms county, Norway. He served as a parish priest for a period in Ramnes in Jarlsberg. He later served as vicar at Brevik in Telemark.
Morten Thrane Esmark described several new minerals principally from Langesundsfjorden in Telemark. He commonly sent interesting specimens to his father, Jens Esmark, who was a professor of mineralogy and geology at the University of Oslo. Morten Thrane Esmark located the first specimens of thorite, from which the element thorium is derived, on the island of Løvøya. His father forwarded the specimen to Swedish chemist Jöns Jacob Berzelius, who confirmed that it was a new mineral which contained a new element. The personal mineral collection of Morten Thrane Esmark was later donated to the Tromsø University Museum.
