The London Missionary Society was an interdenominational evangelical missionary society formed in England in 1795 at the instigation of Welsh Congregationalist minister Edward Williams. It was largely Reformed in outlook, with Congregational missions in Oceania, Africa, and the Americas, although there were also Presbyterians, Methodists, Baptists, and various other Protestants involved. It now forms part of the Council for World Mission.
Around 1900, the London Missionary Society produced a series of glass magic lantern slides, including this one, depicting the missionary efforts of David Livingstone.
