Alexander Berkman (November 21, 1870 – June 28, 1936) was an anarchist known for his political activism and writing. He was a leading member of the anarchist movement in the early 20th century.
Berkman was born in Vilnius in the Russian Empire and immigrated to the United States in 1888. He lived in New York City, where he became involved in the anarchist movement. He was the lover and lifelong friend of anarchist Emma Goldman. In 1892, Berkman attempted to assassinate businessman Henry Clay Frick as an act of propaganda of the deed. Though Frick survived the attempt on his life, Berkman served 14 years in prison. His experience in prison was the basis for his first book, Prison Memoirs of an Anarchist.
