Leroy Eldridge Cleaver (August 31, 1935 – May 1, 1998) was an African American writer and political activist, fashion designer, convicted rapist and an early leader of the Black Panther Party serving as Minister of Information, and while in exile, Head of the International Section of the Panthers. As editor of the official Panthers' newspaper, The Black Panther, Cleaver's influence on the direction of the party was rivaled only by founders Huey P. Newton and Bobby Seale.

While in prison, he wrote a number of philosophical and political essays, first published in Ramparts magazine and then in book form as Soul on Ice.

In the most controversial part of the book, Cleaver acknowledges committing acts of rape, stating that he initially raped black women in the ghetto "for practice" and then embarked on the serial rape of white women. He described these crimes as politically inspired, motivated by a genuine conviction that the rape of white women was "an insurrectionary act". When he began writing Soul on Ice, he unequivocally renounced rape and all his previous reasoning about it.

Despite these controversial admissions, the book was praised by The New York Times Book Review as "brilliant and revealing".

The essays in Soul on Ice are divided into four thematic sections: "Letters from Prison", describing Cleaver's experiences with and thoughts on crime and prisons; "Blood of the Beast", discussing race relations and promoting black liberation ideology; "Prelude to Love – Three Letters", love letters written to Cleaver's attorney, Beverly Axelrod; and "White Woman, Black Man", on gender relations, black masculinity, and sexuality.
