 In India, Rambo served as the medical director of the Christian Hospital Mungeli and initiated the development of eye camps, groups of medical surgeons that visited towns, set up cataract removal stations, and restored sight to the partially blind through eye surgeries.
 Under Rambo's leadership, the hospital conducted over 150 eye camps in over 25 villages.
 It is estimated that the implementation of these eye camps helped restore sight to over 40,000 patients.

Saint Ursula (Latin for "little female bear") is a Romano-British Christian saint.
 Her feast day in the pre-1970 General Roman Calendar is October 21.

 The Foreign Christian Missionary Society was established toward the end of 1876.
 The Society was organized for three main reasons:
Saint Patrick (Latin: "Patricius" ; Irish: "Pádraig" ] ; Welsh: "Padrig" ) was a fifth-century Romano-British Christian missionary and bishop in Ireland.
 Known as the "Apostle of Ireland", he is the primary patron saint of Ireland, along with saints Brigit of Kildare and Columba.

Dr. Ruth V. Hemenway (1894–9 July 1974) was an American Christian medical missionary known for her work in China from 1924 to 1941.
 Despite the limited opportunities available to women in this time period, Hemenway attended medical school and interned at Woman’s Medical College of Pennsylvania.
 Her own experiences and firm belief in Christianity inspired her to improve the health care for women in Fukien, a province of China.
 In the midst of political unrest, Hemenway established several clinics and medical facilities in rural China, vastly improving the prenatal care in the area.
 As Hemenway spent more time in China, observing traditional village life in the decisive years before the Communist Revolution, she began to feel more isolated from the Christian faith.
 She spent the remainder of her time advocating the implementation of modern knowledge in order to improve Chinese society.
Caroline Neville Pearre (1834-1910) began the Christian Women's Board of Missions in 1874 after being called to do so during her morning prayers.
 Pearre was living in Iowa City, Iowa at the time, having taught at Christian colleges in Missouri, Kentucky and Ohio.
 The wife of a Disciples of Christ pastor, Pearre organized a missionary society in her own church in Iowa City.
 Friends of hers in other Christian churches organized similar missionary societies in their churches.
 These various societies united and formed the American Christian Missionary Society which became the Christian Women’s Board of Missions (CWBM).
The Church of England Zenana Missionary Society (CEZMS; founded 1880), also known as the Church of England Zenana Mission, was a British Anglican Christian missionary society established to spread Christianity in India.

William Henry Temple Gairdner (July 31, 1873 – May 22, 1928) was a British Christian missionary with the Church Missionary Society in Cairo, Egypt.
 His entire life was dedicated to service in Egypt as he himself commented when he was first preparing to leave.
 While in Cairo he partnered with his dear friend Douglas M. Thornton in order to reach educated Muslims with the gospel of Jesus Christ.
 This dynamic duo held many lectures in their home, Beit Arabi Pasha, and wrote a weekly magazine titled "Orient and Occident".
 After Thornton's death in 1907 Gairdner continued his work in Cairo but was never able to recapture the amount of work that was accomplished when Thornton was at his side.
 It was this lack of help that would plague his ministry until the day of his death in 1928.
 Gairdner was a prolific writer and scholar of Arabic.
 He showed much promise to contribute greatly in theological and scholarly circles of Islam but instead chose to serve the local church in Cairo.
