Historic Images of the Smithsonian


Dean of Alaskan explorations, William Healey Dall, 1845-1927, began his scientific career as a member of the Scientific Corps of the Alaskan Western Union Telegraph Expedition in 1865. While on the Western Union Telegraph Expedition, 1865-1868, Dall conducted a geological and biological survey of Alaska to determine a feasible route for a telegraph cable across the Bering Strait. A member of the Expedition's Scientific Corps, he assumed leadership of the Expedition after the death of Robert Kennicott in 1866. In 1871 he was appointed to the United States Coast & Geodetic Survey, where he continued his studies on Alaska and the northern Pacific Coast. Dall left the Coast Survey in 1884 to transfer to the United States Geological Survey as a paleontologist. A position he held until 1925. Concurrently, as a malacologist he assembled and described some of the collections of mollusca and other organisms held by the United States National Museum, and served as Honorary Curator of the Museum's Division of Mollusks from 1880 until his death.
