"William "Big Bill" Haywood, the WFM's secretary-treasurer, began working in an Idaho silver mine at the age of nine; as an adult, he was one of the most fearsome and effective union organizers in America, a strapping frontier socialist with a missing eye and a booming, powerful voice that carried throughout the nation's union halls and picket lines. He went on to help cofound the IWW, lead influential strikes in the Northeast (including the 1912 Lawrence Textile Strike), fight for the eight-hour workday, and later flee the country for Russia after decades of state persecution, but his time with the WFM is what first honed his radical sensibilities and his fervent belief in industrial unionism, the necessity of organizing the entire working class into "One Big Union.""
