Mary Jane Rathbun (June 11, 1860 – April 4, 1943) was an American zoologist who specialized in crustaceans. She worked at the Smithsonian Institution from 1884 until her death. She described more than a thousand new species and subspecies and many higher taxa. Biography Mary Jane Rathbun was born on June 11, 1860, in Buffalo, New York, the youngest of five children of Charles Rathbun and Jane Furey. Her mother died when she was only one year old, and Mary was therefore "thrown on her own resources". She was schooled in Buffalo, graduating in 1878, but never attended college. Rathbun was only tall, and was noted for having a dry sense of humor. Rathbun first saw the ocean in 1881 when she accompanied her brother, Richard Rathbun, to Woods Hole, Massachusetts. He was employed as a scientific assistant to Addison Emery Verrill, alongside Verrill's chief assistant, the carcinologist Sidney Irving Smith. Rathbun helped label, sort and record Smith's specimens, and worked on crustaceans ever since. For three years, Rathbun worked on a voluntary basis for her brother, before being granted a clerkship by Spencer Fullerton Baird at the Smithsonian Institution. She continued to work at the museum, and after 28 years, she was promoted to assistant curator in charge of the Division of Crustacea. In 1915, after her retirement, the Smithsonian Institution designated Rathbun an "Honorary Research Associate", and in 1916 she was granted an honorary master's degree by the University of Pittsburgh. She qualified for a Ph.D. at George Washington University in 1917. Rathbun was a member of the American Association for the Advancement of Science, the Washington Academy of Sciences, and the Wild Flower Preservation Society. She died in Washington, D.C., on April 4, 1943, at the age of 82, from complications associated with a broken hip. Publications Rathbun's first publication was co-written with James Everard Benedict and concerned the genus Panopeus; it was published in 1891. She retired on the last day of 1914, but did not stop working until her death. Her largest work was ("Freshwater crabs"), originally intended as a single publication, but eventually published in three volumes in 1904–1906. She wrote or cowrote 166 papers in total, including descriptions of 1147 new species and subspecies, 63 new genera, one subfamily, 3 families and a superfamily, as well as other nomenclatural novelties. The taxa first described by Rathbun include important commercial species such as the
