Biography/Administrative History
Harry Strachan (1872-1946) and Susan Beamish Strachan (1874-1950) co-founded the Latin American Evangelization Campaign (later
known as the Latin America Mission [LAM]), with headquarters in San Jose, Costa Rica. Harry Strachan served as director until
his retirement in 1945.
Their son, R. Kenneth Strachan (1910–1965), succeeded his father as LAM director and later lectured at Fuller Seminary. He
is known for developing the missionary strategy "Evangelism-in-Depth." It enacted "the Strachan theorem," which stated that
“the expansion of any movement is in direct proportion to its success in mobilizing its total membership in continuous propagation
of its beliefs." Strachan launched EID in Nicaragua (1960) and Guatemala (1962). It has influenced missionary groups in the
Caribbean, South America, India, Japan, the Philippines, and Africa.
W. Dayton Roberts served as Vice President of the Latin American Mission. He served as a missionary with that agency since
1941, as its assistant general director from 1956 to 1965 and as associate general secretary from 1965 to 1971. After the
1971 restructuring of the Mission, he became the first general secretary of the Community.
