Barbara Graham, née Barbara Elaine Wood (June 26, 1923 in Oakland, California – June 3, 1955 at San Quentin) was an American criminal and convicted murderer who was executed in the gas chamber along with two accomplices.
Graham, a prostitute and drug addict nicknamed "Bloody Babs" by the press, was convicted of beating elderly widow Mable Monohan to death during a botched robbery in March 1953 in Burbank, California. She was introduced to her accomplices by her fourth husband, Henry Graham, a career criminal and father of her son, Tommy (she had two sons by her first husband).
Her infamous line before her execution was "Good people are always so sure they are right."
