Victor Luitpold Berger was an Austrian-American socialist politician and journalist who was a founding member of the Social Democratic Party of America and its successor, the Socialist Party of America. Born in the Austrian Empire, Berger immigrated to the United States as a young man and became an important and influential socialist journalist in Wisconsin. He helped establish the so-called Sewer Socialist movement, and also sparked the American Socialist Party's nativist turn. In 1910, he was elected as the first Socialist to the U.S. House of Representatives, representing a district in Milwaukee, Wisconsin.
