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.
Life in solitary confinement means up to 24 hours a day in a cell. People held in disciplinary segregation in federal prisons, for example, typically spend two days a week entirely in isolation and 23 hours a day in their cell for the remaining five days, with one hour outside for exercise.
