Hurdy Gerdy

Gertrude Baines, the world's oldest known person who once quipped she had won the genetic lottery, died Friday at a nursing home. She was 115.

Baines likely suffered a heart attack but an autopsy will be conducted to confirm the cause of death, said her longtime physician, Dr. Charles Witt.

Born in 1894 in Shellman, Ga., Baines claimed the title of the world's oldest living person when a 115-year-old woman, Maria de Jesus, died in Portugal in January.

The oldest person in the world is now Kama Chinen, 114, who lives in Japan, according to Dr. L. Stephen Coles of the Gerontology Research Group, which tracks claims of extreme old age. Chinen was born May 10, 1895, Coles said.

The oldest person who has ever lived is Jeanne-Louise Calment, according to Coles. She was 122 when she died Aug. 4, 1997, in Arles, France.

Baines outlived her entire family, including her only daughter, who died of typhoid.

Baines worked as a maid in Ohio State University dormitories until her retirement and has lived at the Western Convalescent Hospital in Los Angeles for more than 10 years.

Nurses at Western Convalescent Hospital described Baines as a modest woman who liked to watch the "Jerry Springer Show" and eat fried chicken, bacon and ice cream. She refused to use dentures.

"I don't know how she does it. She only has her gums, no teeth," said Susie Exconde, the nursing director who found Baines dead in her bed at about 7:25 a.m.

Witt, her physician, said that when he visited Baines earlier this week, she only complained that her bacon was soggy and arthritis was causing pain in her right knee.

Baines celebrated her birthday at the nursing home April 6 with music, two cakes and a letter from President Barack Obama, whom she voted for in November.
