Life


Dreyer was born in Copenhagen. His father, Lieutenant General John Christopher Dreyer,[3] was the Danish Minister for War and the Navy. When he was 14 he became interested in astronomy and regularly visited Hans Schjellerup at the Copenhagen observatory.[4] He was educated in Copenhagen but in 1874, at the age of 22, he went to Parsonstown, Ireland. There he worked as the assistant of Lord Rosse (the son and successor of the Lord Rosse who built the Leviathan of Parsonstown telescope).


During 1878 he moved to Dunsink, the site of the Trinity College Observatory of Dublin University to work for Robert Stawell Ball. In 1882 he relocated again, this time to Armagh Observatory, where he served as Director until his retirement in 1916. In 1885 he became a British citizen. In 1916 he and his wife Kate moved to Oxford where Dreyer worked on his 15 volume edition of the works of Tycho Brahe, Opera Omnia[5] the last volume of which was published after his death.[citation needed]


He won the Gold Medal of the Royal Astronomical Society in 1916 and served as the society's president from 1923 until 1925. He died on September 14, 1926 in Oxford.


A crater on the far side of the Moon is named after him.



Works


Dreyer compiled the New General Catalogue of Nebulae and Clusters of Stars, basing it on William Herschel's Catalogue of Nebulae, as well as two supplementary Index Catalogues. The NGC and IC catalogue designations are still widely used.


Dreyer was also a historian of astronomy. In 1890 he published a biography of Danish astronomer Tycho Brahe, and in his later years he edited Tycho's publications and unpublished correspondence. History of the Planetary Systems from Thales to Kepler (1905), is currently printed with the title A History of Astronomy from Thales to Kepler.


He co-edited the first official history of the Royal Astronomical Society along with Herbert Hall Turner, History of the Royal Astronomical Society 1820–1920 (1923, reprinted 1987).[6]

Mononymous person

Image
Plato, the Greek philosopher, is universally known by a single name. A mononymous person is an individual who is known and addressed by a single name, or mononym. [a] [b] In some cases, that name has been selected by the individual, who may have originally been given a polynym ("multiple name"). In other cases, it has been determined by the custom of the country [c] or by some interested segment. In the case of historical figures, it may be the only one of the individual's names that has survived and is still known today.
