About Eldorado

History

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.

In the early days, Eldorado had several railroads which came through town. It was at an intersection of the Louisville & Nashville and Cairo & Vincennes railways. The "eastern extremity" of the Belleville & Eldorado Railway (St. Louis Short Line) also came through town. According to Neil Gale, "This settlement, by 1896, could boast of exceptional railroad facilities - The Illinois Central, The Louisville and Nashville, and The Chicago, Cleveland, Cincinnati and St. Louis. When the railroad company placed the name on the station, the name was spelled Eldorado, instead of Elderedo, and it has been known by that name since that time."

The city provided relief efforts to neighboring communities affected by the Ohio River Flood of 1937. Shelter was provided at the city hall, and food provided by the Calvary Baptist Church, led by the Red Cross with local help. When the Leap Day Tornado of 2012 struck nearby Harrisburg, Eldorado immediately provided emergency assistance.
