In the 1830s, as a free black man in Maryland, he worked on a farm and worked to free slaves with a loose group of individuals that is known as the Underground Railroad.

Continuing to work with the Underground Railroad, he was also a typesetter and journalist for radical anti-slavery newspapers before the abolition of slavery in Chicago. Around this time he befriended Frederick Douglass, with whom he would remain close throughout his life. During the American Civil War (1861–1865), he helped recruit black soldiers for Illinois and Massachusetts regiments. After the war, he moved to Denver, where he had spent some time previously. He continued to be a leader in Denver, working to secure blacks the right to vote and equality in education and under the law.
