Which woman was known as the "Miners Angel" for her efforts in union organizing?

Mother Jones earned the nickname "Miners' Angel" due to her significant contributions to labor organizing, particularly in the mining industry. She was a prominent activist for workers' rights in the early 20th century and became known for her relentless campaigning on behalf of coal miners and their families. Her dedication to improving the working conditions and advocating for labor unions made her a revered figure among miners, leading to the affectionate nickname.

Mother Jones often traveled to mining communities to provide support during strikes and organized efforts to unite workers against powerful mining companies. Her ability to rally miners and their families around the cause of labor rights demonstrated her profound influence on labor movements, especially in the mining sector. Her legacy continues to inspire labor activists to this day.

The other individuals mentioned, while also important figures in labor and women's rights movements, were known for different contributions and contexts, which is why they do not hold that specific title associated with efforts in union organization within the mining industry.
