Isabelle Case La Follette (April 21, 1859 – August 18, 1931) was a women's suffrage, peace, and civil rights activist in Wisconsin, United States.

[2] Isabelle Case was born on April 21, 1859, in Summit, Juneau County, Wisconsin, and grew up on her family's farm in Baraboo.

In regard to one of her speeches, local paper Madison Democrat wrote, "... she portrayed the vanity of many of us in trying to make an empty display and neglecting it for true stability and depth of sentiment."

[4] Belle Case and Robert "Bob" La Follette developed an early friendship at University of Wisconsin, their love of reform and rural backgrounds providing common ground for a potential courtship.

While Bob respected Belle's independence, intelligence, and beliefs, he still hoped for a domestic life, writing in his journal, "Oh hasten [the] time when I can see her the center of a home.

But Bob was equally busy serving as the new Dane County district attorney; so much so that he had to "remind" himself to attend their marriage ceremony.

Bob would later remark in his autobiography that she was his "wisest and best counselor",This is not partial judgement, the Progressive leaders of Wisconsin who welcomed her to our conferences would bear witness.

However, when a referendum on women's suffrage in Wisconsin was to be decided in a general election in November 1912, she resigned from the NAWSA to devote her efforts to secure its passage.

[13] Suffragists made appearances at more than 70 county fairs in 1912, including La Follette, who visited seven of them in ten days.

On April 26, 1913, La Follette was among the members of the public who spoke before the U.S. Senate Committee on Women's Suffrage, delivering what the National Magazine described as "a remarkable and forcible address" at the gathering.

Determined to gather public support for the constitutional amendment on women's suffrage, La Follette joined the lecture circuit to address audiences in the Midwest.

In addition, she gave numerous speeches in her home state in 1919 to assure that Wisconsin voters would support ratification of the Nineteenth Amendment.

[3] She died on August 18, 1931, aged 72, in Washington D.C., as the result of a punctured intestine and peritonitis following a routine medical exam.
