About Leila Denmark
Leila Alice Denmark (née Daughtry; February 1, 1898 – April 1, 2012) was an American pediatrician in Atlanta, Georgia. She was the world's oldest practicing pediatrician until her retirement in May 2001 at the age of 103, after 73 years. She was a supercentenarian, living to the age of 114 years, 60 days. A co-developer of the pertussis (whooping cough) vaccine, Denmark was one of the few supercentenarians in history to gain prominence in life for reasons other than longevity. She started treating children in 1928. By the time of her retirement, Denmark was treating grandchildren and great-grandchildren of her first patients. Denmark was the first physician on staff of Henrietta Egleston Hospital, a pediatric hospital, opened on the Emory University campus.
