Johan Ernst Gunnerus

Johan Ernst Gunnerus (1718 – September 23, 1773) was a Norwegian bishop and botanist.

Gunnerus was born at Christiania. He was bishop of Trondheim from 1758, and professor of theology at the university of Copenhagen.

Gunnerus was very interested in natural history and accumulated a large collection of specimens from visits to central and northern Norway. He also encouraged others to send him specimens. Together with the historians Gerhard Schöning and Peter Friederich Suhm he founded The Trondheim Society in 1760. In 1767 it received royal recognition and became the Royal Norwegian Society of Sciences and Letters. Gunnerus was vice President and Director Perpetuus of the Society from 1767 to 1773. The society began publishing its journal in 1761, entitled "Det Trondhiemske Selskabs Skrifter", still published today as "Det Kongelige Norske Videnskabers Selskabs Skrifter". In 1765 Gunnerus published a description of a basking shark in this journal, giving it the scientific name "Squalus maximius".

Gunnerus was the author of "Flora Norvegica" (1766-1776). He contributed notes on the ornithology of northern Norway to Knud Leem's "Beskrivelse over Finmarkens Lapper" (1767), translated into English in 1808 as "An Account of the Laplanders of Finmark". In this Gunnerus was the first person to give a scientific name to the Greenshank.

Gunnerus was the first to suggest that since the northern lights were caused by the Sun, there also had to be auroras around the moon, Venus and Mercury.The plant genus "Gunnera" was named after him.

The standard botanical author abbreviation Gunnerus is applied to plants described by this botanist, who should also appear on this list.
