Biography
Johan Kiær was born in Drammen, Norway. He was the son of parish priest Hagbarth Kiær (1829–1903) and grandson of shipowner and Member of Parliament Hans Andersen Kiær (1795–1867). He was a nephew of Elias C. Kiær (1863–1939) operator of the family company And. H. Kiær & Co. which had been founded by his great-grandfather, Anders Hansen Kiær (1769–1838).

Kiær studied zoology and then paleontology for three years under Professor Karl Alfred von Zittel (1839–1904) at Ludwig Maximilian University of Munich where in 1896 he received his doctorate. In 1909 he was appointed professor of paleontology at the University of Oslo, as the first in Norway to hold such a position. He was also head of the Palaeontological Museum of Oslo which opened in 1920.

His most important publication was his doctoral dissertation from 1906, Das Obersilur im Kristianiagebiete. His most notable work was the excavation of a rich fauna of jawless fish and sea scorpions from the Rudstangen fauna of the Sundvollen Formation in the stratigraphy of the Ringerike Group (1908, 1911, 1924). He also took part in work on Spitsbergen and to Novaya Zemlya. He work covered corals, trilobites, and especially Devonian and Silurian fishes.

Kiær was responsible for the construction of the paleontological section of the Paleontologisk Museum at Tøyen in Oslo. He was an important inspiration for the work of palaeontologist Anatol Heintz (1898–1975) who was director of the Paleontological Museum from 1940.
