"Earthrise" is one of the most famous photographs in history. The picture of the Earth from orbit around the moon was taken by astronaut Bill Anders during Apollo 8. But who gave the picture its iconic name?
I believe the photo essentially received that name by acclamation. Before it came to be regarded as the name of the photo, it was the most natural, obvious, and succinct description of the contents of the photo. I recall seeing that photo in books and magazines with captions like "Earthrise as seen from Apollo 8." My sense is the word's evolution from description to name was a gradual process.
