Input: Consider Input: Question: What was John Holt's career? Passage:Youth activism as a social phenomenon in the United States truly became defined in the mid- to late-nineteenth century when young people began forming labor strikes in response to their working conditions, wages, and hours. Mary Harris "Mother" Jones organized the first youth activism in the U.S., marching 100,000 child miners from the coal mines of Pennsylvania to the U.S. Capitol in Washington, D.C. in 1908. Youth newspaper carriers soon followed. These actions isolated youths' interests in the popular media of the times, and separated young people from their contemporary adult labor counterparts. This separation continued through the 1930s, when the American Youth Congress presented a "Bill of Youth Rights" to the US Congress. Their actions were indicative of a growing student movement present throughout the US from the 1920s through the early 1940s. The 1950s saw the Student Nonviolent Coordinating Committee bring young people into larger movements for civil rights. All the way back in 1959, Rev. Dr. Martin Luther King, Jr. engaged youth activists in protesting against Bull Connor's racist law enforcement practices in Birmingham, Alabama. The youth activism of Tom Hayden, Keith Hefner and other 1960s youth laid a powerful precedent for modern youth activism. John Holt, Myles Horton and Paulo Freire were important in this period. Youthful life and expression defined this era.
