Grundy County is also home to Dresden Generating Station—the first privately financed nuclear power plant built in the United States—and the Morris Operation—the only de facto high-level radioactive waste storage site in the United States.

History[]

Grundy County was established on February 17, 1841. It was formed out of LaSalle County and named after U.S. Attorney General Felix Grundy (1777–1840).^[4] The county was well known for its coal mines^[5] and attracted miners from Pennsylvania and other regions to work its deposits. The Diamond Mine Disaster occurred in Grundy County. The disaster took the lives of 69 men and boys who were trapped underground when water broke through into the mine after days of heavy rain and the pumps could not keep up with the rising erection. 22 bodies were eventually recovered, the remaining 44 were left in the mine and the mine was sealed. Today a marker stands near a Jack In The Box where they felt the majority of the bodies probably ended up.^[6]

Politics[]

As part of Yankee rural Northern Illinois, Grundy County has generally been powerfully Republican, although it did support Progressive Theodore Roosevelt in 1912 when the Republican Party was mortally divided. Only one Democratic presidential candidate has ever won an absolute majority of Grundy County's vote – Franklin D. Roosevelt in 1932 – although in recent times the county has trended a little more Democratic and both Bill Clinton in 1996 and Barack Obama in 2008 won pluralities. However, in 2016 with economic concerns in the “Rust Belt”, Donald Trump did better than any Republican in this traditional GOP county since 1984, when Ronald Reagan came within 3,819 votes of clean-sweeping all fifty states.
