The oldest active ranger in the National Park Service (NPS), who celebrated her 100th birthday in September, announced her retirement on Thursday. The move came "after a decade and a half of sharing her personal experiences and the efforts of women from diverse backgrounds who worked on the World War II Home Front," NPS said in a statement. "To be a part of helping to mark the place where that dramatic trajectory of my own life, combined with others of my generation, will influence the future by the footprints we've left behind has been incredible," Soskin said. "Being a primary source in the sharing of that history – my history – and giving shape to a new national park has been exciting and fulfilling," she added. "It has proven to bring meaning to my final years." For her last day, she provided "an interpretive program to the public" and also spent time with her coworkers.

Her decision to join came after Soskin served as a NPS consultant while they were researching the formation of the park. At the time, she was the only person of color in the room and became an integral part of making sure the park didn't erase its history of racial segregation. Throughout her tours, Soskin often discussed her unique backstory, which includes working at a segregated union hall as a file clerk during World War II and later becoming a political and community activist and songwriter during the civil rights movement. "Though I am not a trained historian — my tours are necessarily a way to share my oral history with the public," Soskin remarked during an interview with TODAY back in 2015. "I tell the story of the African-American workers."
