This collection documents the life and work of the Rev. Henry Hale Bucher, Sr. and his wife Louise Catron Scott Bucher, who served as Presbyterian missionaries in China and the Philippines, and as fraternal workers in Thailand from 1929 to 1972. The bulk of the collection consists of correspondence from the Buchers to their families and their children. Writings of the Buchers, biographical documentation, collected material, photographs, and audio materials document their missionary work as well as their time in the Santo Tomas and Los Baños internment camps in the Philippines during World War II, when forced to leave China by the Japanese occupation.
