Elliott Ladd Coues (; September 9, 1842 – December 25, 1899) was an American army surgeon, historian, ornithologist, and author.[1] He led surveys of the Arizona Territory, and later as secretary of the United States Geological and Geographical Survey of the Territories. He founded the American Ornithological Union in 1883, and was editor of its publication, The Auk.
Coues was born in Portsmouth, New Hampshire, to Samuel Elliott Coues and Charlotte Haven Ladd Coues.[2] He graduated at Columbian University, Washington, D.C., in 1861, and at the medical school of that institution in 1863. He served as a medical cadet in Washington in 1862–1863, and in 1864 was appointed assistant-surgeon in the regular army, and assigned to Fort Whipple, Arizona. While there was not yet any legal provision for divorce under its laws, the 1st Arizona State Legislature granted Coues an annulment of his marriage to Sarah A. Richardson.[3] [4] His marriage to Jeannie Augusta McKenney ended in divorce in 1886,[5] and he married the widow, Mary Emily Bates in October 1887.[6]
In 1872, he published his Key to North American Birds, which, revised and rewritten in 1884 and 1901, did much to promote the systematic study of ornithology in America. In 1883, he was one of three members of the Nuttall Ornithological Club that put out a call to form a "Union of American Ornithologists". This would become the American Ornithologists' Union, with Coues as a founding member. He edited its journal, The Auk, and several other ornithological periodicals.[7] His work was instrumental in establishing the currently accepted standards of trinomial nomenclature – the taxonomic classification of subspecies – in ornithology, and ultimately the whole of zoology. During 1873–1876 Coues was attached as surgeon and naturalist to the United States Northern Boundary Commission, and from 1876 to 1880 he was secretary and naturalist to the United States Geological and Geographical Survey of the Territories, the publications of which he edited. He was lecturer on anatomy in the medical school of the Columbian University from 1877 to 1882, and professor of anatomy there from 1882 to 1887.
He was a careful bibliographer and in his work on the Birds of the Colorado Valley, he included a special section on swallows and attempted to resolve whether they migrated in winter or hibernated under lakes as was believed at the time:
He was elected as a member of the American Philosophical Society in 1878.[8] He resigned from the army in 1881 to devote himself entirely to scientific research. In 1899 he died in Baltimore, Maryland.
Grace's warbler, a species of bird, was discovered by Elliott Coues in the Rocky Mountains in 1864. He requested that the new species be named after his 18-year-old sister, Grace Darling Coues, and his request was honored when Spencer Fullerton Baird described the species scientifically in 1865.
In addition to ornithology he did valuable work in mammalogy; his book Fur-Bearing Animals (1877) being distinguished by the accuracy and completeness of its description of species, several of which were already becoming rare. Odocoileus virginianus couesi, the Coues' white-tailed deer is named after him. Campylorhynchus brunneicapillus couesi, a subspecies of the Cactus wren, is named after him and is specifically the state bird of Arizona, recognizing Coues' contributions to natural surveys of early Arizona.[9] [10] [11]
Coues took an interest in spiritualism and began speculations in Theosophy. He was a friend of Alfred Russel Wallace and they had attended séances with the medium Pierre L. O. A. Keeler.[12]
He felt the inadequacy of formal orthodox science in dealing with the deeper problems of human life and destiny. Convinced by the principles of evolution, he believed that these principles may be capable of being applied in psychical research and he proposed to use it to explain obscure phenomena such as hypnotism, clairvoyance and telepathy.[13] He claimed to have witnessed levitation of objects and developed a theory to explain the phenomenon,[14] publishing an article about his telekinetic theory of levitation in the first issue of The Metaphysical Magazine (1895).[15]
Coues joined the Theosophical Society in July, 1884.[16] He visited Helena Blavatsky in Europe. He founded the Gnostic Theosophical Society of Washington, and in 1890 became the president of the Theosophical Society. He later became highly critical of Blavatsky and lost interest in the Theosophical movement.[13]
Coues wrote an attack on Blavatsky entitled "Blavatsky Unveiled!" in The Sun newspaper on July 20, 1890. The article prompted Blavatsky to file a legal suit against Coues and the newspaper but it was terminated as she died in 1891. He fell out with Theosophical leaders such as William Quan Judge and was expelled from the Theosophical Society in June 1899 for "untheosophical conduct".[16] [17] Coues retained interest in oriental religious thought and later studied Islam.[16]
Among his publications are:
Coues also contributed numerous articles to the Century Dictionary, wrote for various encyclopaedias, and edited:
