Jamaican Baptist teacher and evangelist in Cameroon.
Born a slave, Johnson was one of several pioneer freed Jamaicans who in 1843 traveled to Clarence on the island of Fernando Po and in 1845 settled in Douala, along the Cameroon river estuary. In 1853 Baptist Missionary Society missionary Alfred Saker (1814-1880) baptized her and encouraged her and her husband, Sam Johnson, to open a mission station in Douala. As a colleague of another Jamaican missionary, Joseph Jackson Fuller (1825-1908), Mammie Johnson helped lay the foundations of Protestant work in Cameroon. They studied the native languages, undertook translation work, formed churches, and provided services in the areas of medicine, education, agriculture, and industrial training. As part of the Jamaican pastoral team, Johnson pioneered women's work and encouraged formation of indigenous church leadership in Cameroon.
British Baptist missionary colleagues gratefully acknowledged her care of the sick and of missionary children. At her death, they remembered Johnson as an inspiring Christian lay worker.
