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. Braidwood endured one major coal mining disaster.[6] Most of the coal was destined for the Chicago area.
