Jack Henry Abbott (January 21, 1944 – February 10, 2002) was an American criminal and author. He was released from prison in 1981, while serving sentences for forgery, manslaughter and bank robbery, after gaining praise for his writing and being lauded by a number of high-profile literary critics, including author Norman Mailer. Six weeks after being released, he claims to have mistook the intentions of a person who displayed no threat objectively, fatally stabbed him, was convicted of manslaughter, and returned to prison, where he committed suicide in 2002. He self-described his life as being a "state raised convict", spending much of his life since age 12 in confinement in state facilities, including solitary confinement. He wrote that because of confinement with other violent offenders from whom he could not escape, he developed a subjective perspective that every encounter was potentially threatened.
