The History of Everest
Above, left: The first printed map naming Peak XV as Mount Everest. It appeared with Col. A. S. Waugh’s paper on “Mounts Everest and Deodanga” in the Proceedings of the Royal Geographical Society, Volume 2, 1857–58.

For the first time, this scientific endeavor allowed an accurate framework for a map of India. This in turn unraveled the heights of the Himalayan mountains and established Mount Everest as the highest mountain in the world.
