Mary Harris Jones was born in 1830 in County Cork, Ireland. Her family left the devastation brought by the Irish Potato Famine and emigrated westward, first to Canada and then to American. Tragedy befell Jones when she lost her family to a yellow fever outbreak and then her home in the great Chicago fire. She went on to become a labor activist and was given the nickname “Mother Jones.” A champion of the working class, Jones was a campaigner for the United Mine Workers Union, founded the Social Democratic Party and helped establish the Industrial Workers of the World. Jones died in 1930.
