Title: Historical Spencer Stereoviews of Jupiter Inlet


Lighthouse keepers Frederick Whitehead and Melville Spencer took more than a hundred photographs in Southeast Florida during 1876-1889, selling many of them as stereoviews. Stereographs consist of two nearly identical photographs or photomechanical prints, paired to produce the illusion of a single three-dimensional image, usually when viewed through a stereoscope. These images show rare views of Southeast Florida’s wilderness, pioneers, early tourists, and flora & fauna. They are a remarkable intersection of nature, history, and art. Come see some of the earliest known photos of the Jupiter Inlet Lighthouse and Loxahatchee River.
