Before coming to Western Washington, E.M. Sammis had a business in Visalia, California, making portrait daguerreotypes, ambrotypes, and carte-de-visite photographs. By 1860, he was working in Olympia, and by 1865, he had moved to Seattle. Sammis made photographs not only of local people but also of the city and various events. These images would probably have been popular not just locally, but also in larger cities like San Francisco, where people craved news of more remote locations.
Sammis is most famous for his photograph of Chief Seattle (si?al), made in 1865. Early historian Clarence Bagley, a friend of Sammis, was visiting the photographer in his studio one day when Chief Seattle happened to walk by. Sammis ran out and asked Seattle to come in and be photographed; the chief acquiesced. Bagley assisted Sammis in making a batch of prints, and before long the image was being sold all over the country.
