George Sherwood Eddy (1871–1963) was a leading American Protestant missionary, administrator and educator. He was a prolific author and indefatigable traveler. His main achievement was to link and finance networks of intellectuals across the globe, especially Christian leaders in Asia and the Middle East. He enabled missionaries to better understand and even think like the people they were serving. His long-term impact on the Protestant communities in the United States, and in the Third World, was long lasting. From the 1930s onwards, he became a Christian socialist.

The Student Volunteer Movement for Foreign Missions was an organization founded in 1886 that sought to recruit college and university students in the United States for missionary service abroad. It also sought to publicize and encourage the missionary enterprise in general. Arthur Tappan Pierson was the primary early leader.
