Hendrina Hospers, daughter of Henry Hospers, served as a missionary in the Reformed Church of America. She first taught school near Orange City, Iowa, then moved to Fort Sill, Oklahoma in 1905, to work with the Chiricahua Apache, including Geronimo, during their imprisonment there. She traveled to Mescalero, New Mexico, when the Apache people were released in 1913. In 1914, Ms. Hospers began her mission work on the Jicarilla Apache Reservation in northern New Mexico; she remained there until her retirement in 1946.
