Dr. Frank C. Laubach, working among remote tribes people in the Philippines, invents a technique that teaches reading by linking pictures with words and symbols. When the Depression leads to funding cuts, Dr. Laubach tells the chieftain that he can’t carry on. The chieftain declares that the program will continue, telling his tribe that everyone who has learned to read must teach someone else—or be killed. From this comes the Laubach motto, “Each One Teach One.”
