Donaldson’s, also known as William Donaldson and Company and L. S. Donaldson’s, was a Minneapolis department store located on Nicollet Avenue and Sixth Street. Started by two immigrant brothers, the company grew to be one of the major retail chains in the Twin Cities, rivaling Dayton’s for much of the twentieth century.
In 1939, Frederick McKinley Jones patented the world’s first successful refrigerated transportation system. At the time, he was working for the Minneapolis-based company U.S. Thermo Control. Two years later, he released an improved version, the Model C, which revolutionized the agriculture and military industries.
