Missionary pioneer. Betty began her career as secretary to Robert C. McQuilkin. Later, alongside ministry partner Mary Beam (1934), she pioneered Gospel witness among the Uduk people of the Sudan and planted an enduring church there. With intrepid grit and excellence, Betty and Mary learned the language, translated Scripture, taught the people to read, established an orphanage, midwifed, nurtured the church, and modeled the life of faith before the people. Upon retiring from additional teaching and church planting in Kenya, Beam and Cridland founded the Bible Alliance, which provides audiocassette tapes of the Scripture in many of the world's yet unwritten languages. Betty passed away in 2003.
