William Thompson
Born	(1805-12-02)2 December 1805
Died	17 February 1852(1852-02-17) (aged 46)
Known for	Ornithologist, marine biologist, and author

William Thompson (2 December 1805 – 17 February 1852) was an Irish naturalist celebrated for his founding studies of the natural history of Ireland, especially in ornithology and marine biology. Thompson published numerous notes on the distribution, breeding, eggs, habitat, song, plumage, behaviour, nesting and food of birds. These formed the basis of his four-volume The Natural History of Ireland, and were much used by contemporary and later authors such as Francis Orpen Morris.^[1]

Thompson was born in the booming maritime city of Belfast, Ireland, the eldest son of a linen merchant, whose wealth would later permit Thompson to fund his own research without an academic affiliation. Thompson attended the newly formed Royal Belfast Academical Institution, where he got a degree in Biological Science. Founded by, amongst others, John Templeton, the school had a strong natural history section that produced a cohort of prominent naturalists. In 1826 he went on a Grand Tour accompanied by cousin George Langtry, a Fortwilliam, Belfast shipowner.^[2] They starting in the Netherlands then travelled through Belgium down the Rhine to Switzerland and on to Rome and Naples. They returned via Florence, Geneva and Paris.

Thompson's first scientific paper, The Birds of the Copeland Islands, was published in 1827 shortly after he joined the Belfast Natural History Society. In these years he became a member of the Belfast Literary Society.^[3][4][5]

William Thompson was a man of regular habits. For four hours after breakfast he was engaged in scientific research, preparation for the press and correspondence. Exercise for two or three hours followed. The interval between dinner and tea was given to the literature of the day and when the claims of local societies left him free he would retire to the study for two or three additional hours of scientific work. With spring came a visit to London where he enlarged his taste for literature, history, biography and the fine arts as well as science. He also visited most of the scenic parts of England and Scotland. In the summer the seaside with family and then in the Autumn tours with friends, attendance at meetings of the British Association and to shooting quarters in Scotland.^[6]

Thompson contributed up-to-date information on the birds of Ireland to Selby's The Magazine of Zoology and Botany, The Annals of Natural History, The Magazine of Natural History, and the Annals and Magazine of Natural History, and prepared the first comprehensive list of Ireland's birds for the 1840 meeting of the British Association for the Advancement of Science at Glasgow. Other work, primarily about birds, was published in the Proceedings of the Zoological Society of London and the London and Edinburgh Philosophical Journal. These papers formed the basis of his seminal work—The Natural History of Ireland—published in four volumes between 1849 and 1851.

Thompson either owned or had access to a very comprehensive ornithological library exemplared by the Ornithological Dictionary, Le Règne Animal, Selby's Illustrations of British Ornithology, Coenraad Jacob Temminck's Manuel d'ornithologie ou Tableau systématique des oiseaux qui se trouvent en Europe (Sepps & Dufour, Amsterdam, Paris 1815–40), William Edward Parry, 1821 Journal of a Voyage for the Discovery of a North-West Passage from the Atlantic to the Pacific; Performed in the years 1819–'20, in His Majecty's Ships Hecla and Griper ... with an Appendix Containing the Scientific and Other Observations London (1821), William John Swainson and John Richardson, 1831. Fauna boreali-Americana: part second, the birds, Charles Lucien Bonaparte's Synopsis of the Birds of the United States, Peter Simon Pallas' Zoographia Russo-Asiatica. His other tool was his own and other private bird collections and those of the museums in Belfast and Dublin.

The major bird publications are the 1841 Report on the fauna of Ireland (Vertebrata) for the British Association for the Advancement of Science which is an early biogeographic work contrasting the vertebrates of Britain and Ireland. Thompson notes that with a few exceptions the native birds of Britain as then accepted by Jardine and Selby are all found in Ireland. ^[7] and The Natural History of Ireland is, in the section on birds, a Monograph with a literary style, sometimes anecdotal giving information on anatomy, plumage, behaviour, nesting and breeding, seasonality and distribution.

Thompson documented many rare in Ireland bird species, variously collected by his network of correspondents. Among birds these included the first Irish occurrences of Bonaparte's Gull and American Bittern.He was a sceptical observer writing on the Red Kite 'The name of "Kite" appears commonly in the catalogues of birds given in the Statistical Surveys of the Irish counties, and elsewhere; but, as the larger species of the falconidae are in some places called Kite and Glead, as well as Goshawk or Goose-hawk, there can be no doubt that the buzzard, or some common species, was meant.^[8]

In 1834 Thompson began studying the distribution of marine animals in space (depth range) and time (seasonality). His first research was with Edward Forbes conducting dredging in the Irish Sea. Other participants were Robert MacAndrew, John Gwyn Jeffreys, the Yoxford, Suffolk shell collector George Barlee (1794-1861) and his fellow Irishmen Robert Ball, Edmund Getty and George Crawford Hyndman. In 1835 he travelled in France, Switzerland and Germany with Forbes. Then in 1841 he joined Forbes and Thomas Abel Brimage Spratt on the Beacon commanded by Thomas Graves and working in the Mediterranean and Aegean. The expedition lasted eighteen months and conducted more than one hundred dredging operations at depths varying from 1 to 130 fathoms, as well as shore-based studies.^[9] Thompson focused on the depth range of algae, his main collection of which is in the Ulster Museum herbarium and consists of five large albums^{[nb 1]} containing specimens collected by Thompson himself, William Henry Harvey, Moon, D. Landsborough, Robert Ball, Thomas Coulter, George Crawford Hyndman, William McCalla and many others. His records are also reported by others such as Gifford (1853):- Griffithsia simplicifilum from "...Isle of Wight, in August, 1841, by Messers. R.Ball. and W. Thompson."^[10]

George Dickie's Flora of Ulster contains records of Thompson's frequent botanical contributions and his Hortus Siccus and he is mentioned in William Baird's Natural History of British Entomostraca.

Thompson corresponded extensively on all aspects of natural history with naturalists in both Britain and Ireland, including with zoologist Thomas Bell who was at the heart of the English scientific establishment and two of the "Grandees" of the Zoological Society, Nicholas Aylward Vigors, William Ogilby.

As Thompson's reputation spread, information was passed to him by interested observers all over Ireland. However his health became poor around 1847 or 1848, when he was 42, and he suffered from heart trouble from 1847. In 1852 Thompson died of a heart attack in London^[11] where he had been tended by his friends William Yarrell, author of British Birds, Edward Forbes, Edwin Lankester, of the Ray Society and George Busk. He died unmarried.

Excerpts from Thompson's letters and his notes were edited and published as the fourth volume of The Natural History of Ireland, which focused on invertebrates and non-avian vertebrates, by George Dickie, James Ramsey Garrett and Robert Patterson in 1856, four years after his death.
