DeKalb is a city in DeKalb County, Illinois, United States. About 40,000 people lived there in 2020. The city is named after Johann de Kalb, a brave war hero from long ago. He fought during the American Revolutionary War.

Today, DeKalb still has some farm-related businesses. It also has many health and service jobs. The biggest employer in the city is Northern Illinois University, which started in 1895. DeKalb is about 65 miles (105 km) west of downtown Chicago.

History of DeKalb

DeKalb was first called Huntley's Grove. It was officially mapped out in 1853. The city got its name from Baron Johann de Kalb. He was a major general in the American Revolutionary War. The first church in DeKalb was started in 1844.
In 1846, a stagecoach route connected Chicago to DeKalb and other towns. A post office opened in DeKalb in 1849. The first railroad tracks reached the city in 1853.
Barbed Wire and Farming Innovations
Barbed wire was a very important product in DeKalb's history. Joseph Glidden (1813–1906) lived in DeKalb. In 1874, he received a special paper called a patent. This patent was for his invention of the common double-strand barbed wire. This type of wire is still used all over the world today.
Glidden and Isaac L. Ellwood (1833–1910) started making barbed wire in DeKalb. Their first company was called the Barb Fence Company. Later, their companies grew and merged with bigger ones. Glidden and Ellwood also helped start the state teachers college. This college later became Northern Illinois University.
DeKalb also played a big part in developing special hybrid corn. This type of corn produces more crops. The DeKalb Genetics Corporation started making large amounts of high-yield corn seeds in 1934. For many years, more American farmers planted DeKalb hybrid corn than any other brand. The company's logo was a flying ear of corn. Today, the DeKalb brand of farm products is owned by a company called Bayer.
Geography and Climate
DeKalb is located in northern Illinois. It is about 65 miles (105 km) west of downtown Chicago. It is also 30 miles (48 km) southeast of Rockford. The South Branch Kishwaukee River flows north through DeKalb.

On August 24, 2007, the Kishwaukee River in DeKalb flooded. The water rose very high, causing a lot of damage. This was one of the highest flood levels ever recorded for the river.
