Betty Reid Soskin, the country's oldest active National Park Service ranger, retired Thursday at the age of 100.
As a ranger, Soskin shared her personal experiences with the public as an African-American woman working on the World War II home front in Richmond, California, illuminating the stories of women from diverse backgrounds who joined the civilian war effort.
Soskin, who celebrated her birthday in September, spent her last day on the job heading up an interpretive program for the public and visiting co-workers at Rosie the Riveter/WWII Home Front National Historical Park in Richmond, according to the park service.
