Chasing Shadows, Then and Now: The Solar Eclipses of 1878 and 2017 on July 29th at 7pm


On August 21, the United States will enjoy a rare eclipse of the sun. In Colorado it will appear as a partial eclipse, but spectators along a 70-mile-wide path from Oregon to South Carolina will be treated to a total solar eclipse, the most awe-inspiring sight in nature. Boulder author and science journalist David Baron will offer guidance on how to view the upcoming eclipse, and he will tell the forgotten tale of a similar eclipse that crossed America’s Wild West in 1878. Among the eclipse chasers that year were Vassar astronomer Maria Mitchell, who headed an all-female expedition to Denver to show what women could do in science, and a young Thomas Edison, who after observing the eclipse in Wyoming soon lit the world with his most famous invention. Baron recounts the story in his new book, American Eclipse: A Nation’s Epic Race to Catch the Shadow of the Moon and Win the Glory of the World, which will be available for purchase and signing after the talk.
