Donald B. MacMillan first went to the Arctic as a member of Robert Peary’s 1908-09 North Pole Expedition and continued traveling to, working in, and photographing the region until 1954. Between trips, he raised funds for his expeditions by lecturing throughout the country. He illustrated these lectures with glass lantern slides made, mostly, from a selection of his photographic images. Donald and his wife Miriam donated this entire collection of over 2,000 slides to the museum when it was founded in 1967. Now, this incredible resource is available to the public at MacMillan's Glass Lantern Slides.
