Carl Sagan

"He sought a way to preserve the past. John Hershel was one of the founders of a new form of time travel.... a means to capture light and memories. He actually coined a word for it... photography. When you think about it, photography is a form of time travel. This man is staring at us from across the centuries, a ghost preserved by light."
