Three total solar eclipses have crossed Wyoming since territorial times—in 1878, 1889 and 1918. Two in particular drew prominent astronomers and scientific discoveries. These are especially interesting now, with the August 21, 2017 eclipse likely to draw huge crowds to a very different Wyoming from the one that last saw moon shadows in daytime.
The yarn that Thomas Edison dreamed up the idea of a bamboo filament for the incandescent electric light bulb while staring into a Wyoming campfire is almost certainly not true. He did come to Rawlins, Wyoming Territory in 1878, however, as part of an astronomical expedition, and he did go fishing afterwards. The rest of the facts still make for a pretty interesting story.
