Mary Foust was the daughter of Daniel Foust. She never left East Tennessee and lived to be around 100 years old. When President Teddy Roosevelt was visiting Tennessee she was considered the oldest living American at the time and he traveled to meet her and eat one of her home cooked meals. Mary was famous for living an unchanged lifestyle that was a living window into the past. Her loom is now in the "Museum of Appalachia" near where she once lived.
