DeKalb was originally known as Huntley's Grove, named after Russell Huntley, an early settler who was one of its founders. The area had also been known as Buena Vista and DeKalb Center, before settling on the name DeKalb in 1881. The name was derived from Baron Johann DeKalb (1721-1780), a German soldier who served under Washington at Valley Forge and died a Revolutionary War hero. Three august DeKalb men are credited with the invention of barbed wire and began manufacturing it in 1873. Today DeKalb is a world leader in hybrid seed development and genetic research, as well as the home of Northern Illinois University.
