society and recommended Robert for the job. After the excursion, Kennicott published a catalog of the animals of Cook County. The first new animal species identified by Kennicott was a Northern Illinois snake, which he sent to Baird. Baird suggested that Kennicott name the animal after Kirtland, Regina kirtlandii (today Clonophis kirtlandii). Kennicott published a three-part paper from 1856 to 1858 entitled "The Quadrupeds of Illinois, Injurious and Beneficial to the Farmer". In it, Kennicott pleaded with farmers to first study the habits of wild animals before attempting to eradicate them. The Board of Trustees of Northwestern University approached Kennicott in early 1857, asking him to help them create a natural history museum. Later that year, Kennicott co-founded the Chicago Academy of Sciences. For the next two winters, Kennicott worked at the Smithsonian in Washington, D.C., helping Baird organize its amphibian and reptile collections. There, he met William Stimpson and became a part of the Megatherium Club. In April 1859 he set off on an expedition to collect natural history specimens in the subarctic boreal forests of northwestern Canada in what is now the Mackenzie and Yukon river valleys and in the Arctic tundra beyond. Kennicott became popular with Hudson's Bay Company fur traders in the area and encouraged them to collect and send natural history specimens and First Nations artifacts to the Smithsonian. He returned to Washington at the end of 1862. Kennicott considered joining the Union Army in the Civil War, but was convinced otherwise, sending a substitute. Robert and his younger brother lived in the Smithsonian Castle during the war along with Edward Drinker Cope and other noted naturalists. He returned to Illinois in 1863 to tend to his ailing father, who died later that year. While working at the Smithsonian Institution under Assistant Secretary Spencer F. Baird, Robert Kennicott wrote the original descriptions of many new snake taxa brought back by expeditions to the American West. He also collected snake specimens including with his specimen collecting first cousin Helen L. Teunisson. He subsequently named the subspecies Carphophis amoenus helenae in her honor. In 1864 the Western Union Telegraph Expedition was mounted to find a possible route for a telegraph line between North America and Russia by way of the Bering Sea. Kennicott was selected as the scientist for this expedition, and the party of naturalists sent to assist him included W.H. Dall. The expedition arrived in
