Dr. Evermor's Forevertron is the 2nd largest scrap metal sculpture in the world (after Gary Greff's Geese In Flight), standing 50 ft. (15,2 m.) high and 120 ft. (36,5 m.) wide, and weighing 300 tons. Built in the 1980s, it is housed in Dr. Evermor's Art Park on Highway 12, in the town of Sumpter, in Sauk County, Wisconsin, United States.
The sculpture incorporates two Thomas Edison dynamos from the 1880s, lightning rods, high-voltage components from 1920s power plants, scrap from the nearby Badger Army Ammunition Plant, and the decontamination chamber from the Apollo 11 spacecraft. Its creator, Tom Every (1938 - 2020), was born in Brooklyn, Wisconsin and was a demolition expert who spent decades collecting antique machinery for the sculpture and the surrounding fiction that justifies it. According to Every, Dr. Evermor was a Victorian inventor who designed the Forevertron to launch himself, "into the heavens on a magnetic lightning force beam." The Forevertron, despite its size and weight, was designed to be relocatable to a different site—the sculpture is built in sections that are connected by bolts and pins.
