Herman Wallace was serving a 50-year sentence for armed robbery when he was convicted, along with fellow inmate Albert Woodfox, for the murder of a prison guard at the Louisiana State Penitentiary in 1972. Wallace spent 41 years in solitary confinement.
Solitary confinement is the practice of isolating people in closed cells for 22-24 hours a day, virtually free of human contact, for periods of time ranging from days to decades. Few prison systems use the term âsolitary confinementâ, instead referring to prison âsegregationâ or placement in ârestrictive housingâ.
