Sophia Marion DeMuth (née Papst) (30 June 1866 – 2 December 1977) was an American verified supercentenarian. She was born in St. Joseph, Missouri. She claimed to have known the notorious Jesse James when she was a child. She later moved to California to work in a shirt factory during the Spanish-American war. Her salary was $11 a week.
In 1899, she married farmer and cattleman Oliver Demuth and the couple lived in various places such as South Dakota and Illinois before settling down in Ayr, Nebraska. Demuth became a widow in 1965 after Oliver's death at age 101. Sophia then started living with her daughter. On her 110th birthday, it was reported that she still was able to make rugs, that her mind was still sharp and that her physical condition was good.
