Over the years, West Allis has progressed from a busy hamlet on the banks of Honey Creek to a stout industrial city. West Allis came of age in the early 20th century as groups of immigrating Germans, Poles, and Slavs joined original settlers to a build a community that is now quickly approaching 100 years of success and vitality. Home to industrial giants such as the Allis-Chalmers Company and Kearney and Trecker Corporation, West Allis manufactured the machines, parts, and equipment essential to the growth of the nation. The city, host of the Wisconsin State Fair, seamlessly blends industry and community.
