Fredrik Johan Wiik
Fredrik Johan Wiik (born December 16, 1839 in Helsinki , † June 15, 1909 there ) was a Finnish geologist and mineralogist.
Wiik studied in Helsinki and at the Bergakademie Freiberg (1865/66). He received his doctorate in 1865 and became an associate professor in 1867 and from 1877 first full professor of geology and mineralogy at the University of Helsinki (the professorship itself had been established in 1852).
He was the first Finnish geologist to use the petrographic microscope and applied it to the study of the petrology of the Finnish crystalline basement. He was one of the founders of the Geological Society of Finland and its first president. He developed his own atomic theory of crystal structures.
In the last years of his life he published a highly speculative triadic-monistic worldview that represented anti- actualistic views. He died, hammer in hand, alone on a geological excursion.
He was an honorary member of the Mineralogical Society of Great Britain and Ireland and a member of the Finnish Academy of Sciences. The mineral Wiikit is named after him.
Jakob Johannes Sederholm is one of his students .
