The story

from WikipediaRead it all ↗

Eldorado was first platted on May 24, 1858, by a surveyor named Martin D. Gillett. The post office was established on December 8 of that same year. Just before the Civil War, the first businesses were started in the town. The original village was incorporated in 1870. It was founded by Francis Elder and his neighbors who were brothers William and John Reed.
