The city of Anderson is named after Chief William Anderson, whose Indian name was Kikthawenund, meaning "making a noise" or "causing to crack." Early settlers referred to the area as Anderson Town, while the Moravian missionaries called it "The Heathen Town Four Miles Away." It later became Anderstown before the Indiana State Legislature shortened the name to Anderson in 1844. In the spring of 1887, natural gas was discovered in the city. Several industries came to the area, leading to a population explosion. Anderson soon became a "factory town," with General Motors building plants throughout the city. The success of the automobile factories attracted entrepreneurs and made Anderson the economic center of Madison County. From the 1940s through the 1970s, downtown Anderson had its share of family-owned businesses as well as national chain stores like J.C. Penney, Sears & Roebuck, and Montgomery Ward. Today, it remains filled with a rich heritage and continues to grow in a new economic market.
