The Associated Press: Woman who became world's oldest doctor dies at 114: Denmark began her pediatrics practice in her home in Atlanta in 1931 and continued until her retirement in 2001. That year, she earned the distinction of being the world's oldest practicing physician, said Robert Young, senior consultant for gerontology for Guinness World Records. She was also the world's fourth-oldest living person when she died, Young said.
Throughout her career, she always kept her office in or near her home, where children and their parents would show up at all hours in need of care, family members said.
