Mamie Eva Keith

Mamie Eva Walter Keith (March 22, 1873 – September 20, 1986) was an American supercentenarian and the second oldest recognized person in the world from February 21, 1986 until her death seven months later in the Winchester House nursing home,Libertyville, Illinois. Keith was a teacher in an elementary school in Anna, Illinois, where she was born. ,

Keith, who lived in Illinois, was thought to have succeeded the now discredited case of Shigechiyo Izumi of Japan, and was included in the Guinness Book of Records 1987 edition. Until 2012, she was considered the world's oldest living woman in December 1985, when 113-year-old Ollie Bay died in Illinois to her own death 10 months later, but 115-year-old Augusta Holtz was later validated as being born in August 1871.

Keith's father was a veteran of the American Civil War, where he served under Gen. William T. Sherman. Keith is said to have remembered hearing the news of Custer's Last Stand, a battle fought when she was three years old.
