William Frankfurth was born in Germany in 1829. He immigrated to the United States in 1849. After spending a year in Ohio, he moved to Milwaukee in 1850 and found employment with the Pritzlaff Hardware Company. In 1862, he opened his own small retail hardware store on the corner of Third and Chestnut (now W. Juneau Ave.). William expanded into wholesale hardware and moved into a new building at 116-118 Clybourn Street in 1885. The business continued to thrive after William passed away in 1891as other family members, either by birth or marriage, directed the company. Another buildingwas built along N. Plankinton Ave. in 1902 and a seven-story addition followed in 1920. At one point, Frankfurth Hardware wasthe largest hardware wholesaler in the Midwest, but it closed its doors in 1979.
