Mary McKinney

Mary Elizabeth "Mamie" McKinney born Wallace (May 30, 1873 – February 2, 1987) was briefly recognized by Guinness as the world's oldest person. Following the death of fellow 113-year-old Mamie Eva Keith in September 1986, she became the "world's oldest person" according to the Guinness Book of Records. However, her own death five months later in Sacramento, California, meant that she never appeared in the record book, even though her Guinness recognition made the news. She was 113 years and 248 days old at the time of her death.
