During the late 1800s, dairy farmers in Minnesota and other states faced what they considered a serious and immediate threat to their livelihoods: the growing popularity of a butter substitute called oleomargarine. For nearly a century, the dairy industry and its legislative allies waged a series of campaigns to prohibit or limit the manufacture and sale of margarine. No state retained its anti-margarine laws longer than Minnesota.

The Kilmarnock Bookstore in downtown St. Paul brought writers and artists together at the dawn of the Jazz Age and helped inspire some of the best work of their careers. Nearly a hundred years later, the Twin Cities are considered among the most literary cities in the United States.

Paul Wellstone once described himself by saying, “I’m short, I’m Jewish, and I’m a liberal.” He was also a Southerner, a college professor, and a rural community organizer who became a two-term U.S. senator from Minnesota.

In 1977, residents of South Minneapolis mobilized to fight the expansion of adult entertainment businesses along Lake Street. In 1983, after years of unsuccessful protest, these activists sought help from nationally known feminist theorists Catharine MacKinnon and Andrea Dworkin.

On July 27, 1972, two armed, masked men walked into the Orono home of Virginia Lewis Piper and walked out with the forty-nine-year-old woman handcuffed and blindfolded. The next day, her husband, Harry C. Piper Jr., a prominent Twin Cities investment banker, personally delivered a $1 million ransom to the unidentified kidnappers. Four decades later, no one has served a day of prison time for the crime. Except for about four thousand dollars in scattered twenty-dollar bills, the Pipers’ million-dollar ransom has not been recovered.

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.
