Elliott Ladd Coues was an American army surgeon, historian, ornithologist, and author.
Biography
Coues was born in Portsmouth, New Hampshire, to Samuel Elliott Coues and Charlotte Haven Ladd Coues. 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. 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. He was a founding member of the American Ornithologists' Union in 1883. 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 resigned from the army in 1881 to devote himself entirely to scientific research. He was a founder of the American Ornithologists' Union, and edited its organ, The Auk, and several other ornithological periodicals. He died in Baltimore, Maryland. Grace's warbler 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 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.
Spirituality
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. 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. He claimed to have witnessed levitation of objects and developed a theory to explain the phenomenon, publishing an article about his telekinetic theory of levitation in the first issue of The Metaphysical Magazine. Coues joined the Theosophical Society in July, 1884. 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. 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". Coues retained interest in oriental religious thought and later studied Islam.
