Schools
The city of Chadwick and surrounding rural area are a part of a consolidation with neighboring Milledgeville, with the K-3 and High School being in the Milledgeville School building and 4th-8th grades at the Chadwick school building, therefore, forming the Chadwick-Milledgeville Community Unit District #399.
Christ Lutheran School, located in nearby Sterling, serves students of various religious backgrounds from Chadwick to Walnut and from Morrison to Dixon. As part of the largest network of Protestant schools in the US, CLS provides an education for students from age 3 through 8th grade that is focused on all of the core academic subjects while remaining true to the Bible.[7]
History
Chadwick is the youngest community in Carroll County and had its beginnings circa 1853 when Jacob Isenhart built the first house on the prairie.
In 1866, when the Chicago, Burlington and Quincy Railroad extended its line from Aurora to Savanna, no provision was made for town sites, so the St. Paul Land Company was organized to acquire land along the right-of-way. The company decided that 60 acres (240,000 m2) which comprised the original town site and belonged to Alexander Snow of Lanark would be an ideal location. The Land Company offered the Snows $100 per acre but Lanark merchants had persuaded the Snows that their land was worth $125; neither party would yield. When the land company started looking elsewhere the farmers in the community raised $1,500, to make up the difference. The land company named the new town Chadwick in honor of one of its officials. The original plot of the town was filed for record on April 12, 1886.
Decreasing population caused a call to incorporate the town. Incorporation papers for Chadwick were approved on Sept. 26, 1882. Following incorporation a village board was elected and a police magistrate and marshal appointed.
The first railroad station was a manure spreader on the south side of the track equipped with the necessary wiring and telegraph instruments for receiving and sending messages on the movement of trains. A new station was built in 1887. Frank Lacy was the first agent but was a telegraph operator only. There were no tickets for sale and passengers paid their fares on the train. The station was enlarged in 1926.
