At the turn of the 20th century, the population surge plateaued and industry began to stagnate; it was only after World War I that the local economy was able to recover, the result of a number of manufacturing companies setting up shop in the village. New industry, coupled with Melrose Park's prime geographic location next to the Proviso freight yards, led to a steady increase in the number of area jobs. This continued after World War II, with still more companies moving to Melrose Park. Zenith Electronics, Alberto-Culver, Jewel, and International Harvester (now Navistar) are some examples. Many of these companies are still located in Melrose Park and the local industry remains stable, but Alberto-Culver no longer exists and Zenith continues to exist as a brand only today.
