What is the nickname of the electric chair mentioned in the text?

The nickname of the electric chair mentioned in "Just Mercy" is "Yellow Mama." This name reflects not only the color of the electric chair as described in the book but also serves to humanize and highlight the grim reality of capital punishment. The chair is depicted as an unsettling object that embodies the violence of execution, and the nickname captures a certain cultural or regional familiarity with the institution of the electric chair in the American South. The use of a nickname adds a layer of irony and poignancy, emphasizing the dehumanization involved in the process of execution, which is a central theme of Stevenson’s work.
