the use of the electric chair; the use of the electric chair ended the execution of death sentences by counties in Texas. The chair– often euphemistically called "Old Sparky" was constructed by inmates. Between 1924 and 1964, 362 inmates were executed by electrocution. The chair now resides at the Texas Prison Museum, located on Interstate 45 on the north side of Huntsville which features displays of historical items from the prison system, including shanks and other items confiscated from inmates. On one occasion the prison used a facility below the current warden's office as a death row for women. Emma "Straight Eight" Oliver, the first female death row inmate under Texas state jurisdiction, was sentenced to death in 1949. In 1951 her sentence was commuted to life imprisonment. Subsequently the Goree Unit and then the Mountain View Unit were used as women's death rows. Execution procedure Inmates scheduled for execution are brought from death row on the Polunsky Unit to the Walls Unit early in the afternoon of their scheduled execution. Unlike other states, Texas prohibits inmates from getting special last meals (since 2011) because of abuse of the privilege by past prisoners and the rationale that they did not offer a meal to their victims and therefore should not be allowed a special recognition. Inmates can, but are not required to, make a last statement prior to their execution. By law executions are scheduled to begin after 6:00 p.m. Huntsville (Central) time. The inmates are housed until that time about from the door of the execution chamber; the Texas Death House is located at the northeast corner of the Walls Unit, just below the #1 picket. There is no law prohibiting multiple executions in a single day, but this has not happened since August 2000. The execution chamber is a by room with mint green painted walls and a gurney. When Jim Willett was the warden of Huntsville Unit, he added a pillow to the gurney. Texas uses a single lethal dose of pentobarbital to execute condemned inmates. Two adjacent rooms, which view into the execution room through glass windows, house two groups. One room is reserved for the family or families of the crime victim(s). The other is for the family of the condemned. Notable inmates This list does not include death row inmates who were only housed in other units (Ellis, Polunsky, and/or Mountain View) and executed
