Hoover Dam
It is a little known fact that Herbert Hoover was never really interested in becoming president. He actually started his career working as a mining engineer, traveling the world developing mines for various precious metals. At this time, politics was the furthest thing from his mind. His simple ambition, if you can call it simple, was to have a dam named after him, preferably the most famous dam in the Western Hemisphere. Becoming the President of the United States was just, in engineering language, the straightest line between two points.
Too bad Hoover's mostly remembered for causing the Great Depression.
