Geneva, Illinois

Geneva was first settled in the 1830s on an important route from Chicago. Daniel Shaw Haight was the first settler in Geneva. Haight sold his claim in 1835 to James and Charity Herrington, who were influential in the creation of the town of Geneva. A local’s connections with Col. Richard Hamilton, a prominent Cook County politician, led to the naming of Geneva as county seat in 1836. The town was platted a year later and was probably named after Geneva, New York. Before the name Geneva was chosen, the names LaFox, Big Spring, and Herrington’s Ford were used. A courthouse and jail were among the first major works. Geneva was incorporated as a village in 1867. While its site as a county seat attracted attention, the village’s location on the Fox River provided the most economic opportunities. Early goods manufactured in Geneva included cheese, butter, milled grains, and packed meat. The connection of the railroad in 1853 provided increased demand for industry, and by 1900, Appleton Manufacturing, Howell Foundry, Bennet Milling Co., and Pope Glucose Co. became major employers. This resulted in major civic improvement projects such as a pumping stations and water mains in 1896. Geneva was particularly noted for its flux of Swedish immigrants, who comprised half of the population by 1900. A year later, Geneva was connected to other Fox Valley communities through the Aurora, Elgin and Fox River Electric Company.

The Fabyan Windmill is an authentic, working Dutch windmill dating from the 1850s located in Geneva, Kane County, Illinois, just north of Batavia, Illinois, off Illinois Route 25. The five-story wooden smock mill with a stage, which stands 68 feet (21 m) tall, sits upon the onetime estate of Colonel George Fabyan, but is now part of the Kane County Forest Preserve District.

On June 4, 1979, the windmill was listed on the National Register of Historic Places as the Dutch Mill. The following year, the windmill was selected to be on a U.S. postage stamp, as part of a series of five windmills in a stamp booklet called “Windmills USA.” It originally operated as a custom grinding mill.

Riverbank Acoustical Laboratories is a NVLAP accredited acoustical testing agency founded by Wallace Clement Sabine in 1918. The acoustical laboratory building was funded and built by Colonel George Fabyan on his vast Riverbank Estate in Geneva, IL. In the facility’s early days, It also housed a cryptology team that worked to decipher codes from the works of Sir Francis Bacon, Shakespeare, and enemy military communications. It was added to the National Register of Historic Places on November 28, 2003.

The Fabyan Villa Museum houses photographs, the Fabyans’ personal artifact collections, and a limited number of original furnishings, sharing the Riverbank story with the public.
