Chances are you have never heard of Mount Olive, a sleepy little town in Macoupin County, in the central part of Illinois. But its cemetery marks the final resting place of a lady who was once called "the most dangerous woman in America". She was born Mary Harris in Cork, Ireland in 1837, and played a prominent role in America's labor movement. A left-leaning magazine still bears her name today. What is she better known as?

Born Mary Harris in Ireland in May 1837, Mother Jones was a schoolteacher and dressmaker who played a massive role in the labour movement in America in her role as an activist.

When Mary was 10 years old, the famine in Ireland drove her and her family to move to North America, where she later became a teacher. Soon after, she moved to Chicago, where she met and married George E. Jones. Her husband was a member of the National Union of Iron Moulders. Mary had a difficult life, losing her husband and children to yellow fever and later losing her home and possessions in the Great Chicago Fire. This was a turning point for her and resulted in her joining the Knights of Labour and organising strikes. Once the Knights of Labour disbanded, Mary joined the United Mine Workers. It was during those years that she became known as Mother Jones, because she claimed to be older than she was and wore outdated black dresses. She organised more strikes and had run ins with the law due to the violence that usually erupted during these strikes. Mother Jones fought for the rights of workers, including women and children and became known as "the most dangerous woman in America" by Reese Blizzard, the West Virginia district attorney. She died in 1930.
