At an age where most people choose to enjoy retirement, Betty Reid Soskin joined the National Park Service at the age of 85. Today, she is the oldest full-time ranger in the Service, working at the Rosie the Riveter World War II Home Front National Historical Park in Richmond, California. Throughout her lifetime, she has seen many changes: The great-granddaughter of a slave, eventually freed by the Emancipation Proclamation, Soskin served as a file clerk at a Jim Crow segregated union auxiliary at the age of 20. A longtime activist, she later became a well-known songwriter in the Civil Rights Movement. Today, she rarely appears in public without her uniform, hoping to inspire girls to follow in her footsteps.
