Hubert Henry Harrison (April 27, 1883 – December 17, 1927) was a West Indian-American writer, orator, educator, critic, race and class conscious political activist, and radical internationalist based in Harlem, New York. He was described by activist A. Philip Randolph as "the father of Harlem radicalism" and by the historian Joel Augustus Rogers as "the foremost Afro-American intellect of his time." John G. Jackson of American Atheists described him as "The Black Socrates". An immigrant from St. Croix at the age of 17, Harrison played significant roles in the largest radical class and race movements in the United States. In 1912–14, he was the leading Black organizer in the Socialist Party of America. In 1917 he founded the Liberty League and The Voice, the first organization and the first newspaper of the race-conscious "New Negro" movement. From his Liberty League and Voice came the core leadership of individuals and race-conscious program of the Garvey movement. Harrison was a seminal and influential thinker who encouraged the development of class consciousness among workers, black pride, agnostic atheism, secular humanism, social progressivism, and freethought. He was also a self-described "radical internationalist" and contributed significantly to the Caribbean radical tradition. Harrison profoundly influenced a generation of "New Negro" militants, including A. Philip Randolph, Chandler Owen, Marcus Garvey, Richard Benjamin Moore, W. A. Domingo, Williana Burroughs, and Cyril Briggs. Early life Hubert was born to Cecilia Elizabeth Haines, a working-class woman, on Estate Concordia, St. Croix, Danish West Indies. His biological father, Adolphus Harrison, was born enslaved. One account from the 1920s suggested that Harrison's father owned a substantial estate. Harrison's biographer, however, found no such landholding and writes that "there is no indication that Adolphus, a laborer his entire life, ever owned, or even rented, land". As a youth, Harrison knew poverty but also learned of African customs and the Crucian people's rich history of direct action mass struggles. Among his schoolmates was his lifelong friend, the future Crucian labor leader and social activist, D. Hamilton Jackson. In later life Harrison worked with many Virgin Islands-born activists, including James C. Canegata, Anselmo Jackson, Rothschild Francis, Elizabeth Hendrikson, Casper Holstein, and Frank Rudolph Crosswaith. He was especially active in Virgin Island causes after the March 1917 U.S. purchase of the Virgin Islands, and subsequent abuses under the U.S. naval occupation of the islands. Emigration and education Harrison came to New York in 1900 as a
