Image Gallery: William Healey Dall
William Healey Dall was affiliated with the Smithsonian for sixty-two years, first as a scientific assistant on the 1865 Western Union Telegraph Expedition and later as Honorary Curator of Mollusks for the US National Museum. The images of the 1865 expedition staff show a stark contrast between the very young but formal Dall and his adventurous leader, Robert Kennicott.
