First Photograph of a Solar Eclipse

Today in 1854, William and Frederick Langenheim made eight sequential photographs of the first total eclipse of the sun visible in North America since the invention of photography. Although six other daguerreotypists and one calotypist are known to have documented the event, only these seven daguerreotypes survive. In the northern hemisphere, the moon always shadows the sun from right to left during a solar eclipse; these images therefore seem odd because they are, like all uncorrected daguerreotypes, reversed laterally as in a mirror.
