By Samm Van Kirk and Aaron Sturtz, student researchers, Montana State University, Bozeman

Journalist, suffragist, police matron

Born in Chicago in 1887, Bertha T. Chase became involved in the suffrage movement soon after her marriage to Abraham Rosenberg in 1913 in Billings, Montana. In 1914, when the Rosenbergs were living in Lewistown, she gave speeches advocating suffrage in the city and throughout Fergus County. She also worked for the American Society for Equity, delivering speeches at their events.

Rosenberg worked closely with Jeannette Rankin, who would become the first female member of the U.S. House of Representatives. Their work, which was supported by the National American Woman Suffrage Association, focused on setting up women's clubs and gaining support for suffrage in Fergus County, especially in Lewistown.

Rosenberg also made significant contributions to suffrage work in Montana with her involvement at the State Fair in Helena in September 1914. She was the circulation manager of The Suffrage Daily News, a short-lived suffrage paper published during fair week in 1914. Woman suffrage was adopted in Montana later that year.

After the successful conclusion of the statewide suffrage movement, Rosenberg continued to participate in Montana politics. In 1917, she became the Police Matron for Lewistown. Later that year she worked with the Montana Good Government State Central Committee (the successor to the statewide suffrage organization) at their yearly convention, held in Miles City, where she gave a speech about eugenics.

Rosenberg gave birth to a daughter, Grace, in 1919 and moved to New York. While her subsequent activities are unknown, during her time in Montana Rosenberg made important contributions both to the suffrage movement and state politics.
