Frank Charles Laubach (September 2, 1884 – June 11, 1970), from Benton, Pennsylvania was a Congregational Christian missionary educated at Union Theological Seminary and Columbia University, and a mystic known as "The Apostle to the Illiterates."

In 1915 (see Laubach, Thirty Years With the Silent Billion), while working among Muslims at a remote location in the Philippines, he developed the "Each One Teach One" literacy program.

In 1955, he founded Laubach Literacy, which helped introduce about 150,000 Americans to reading each year and had grown to embrace 34 developing countries.

It consists of lyric and poetry with the epic greatly predominating.His emphasis on the use of Easy English for literacy led directly to the development by WEC International in 1962 of an evangelistic paper using his basic vocabulary called SOON!

He also trained ex-missionary Fred Morris in the use of Worldwide Easy English for his Bible teaching commentaries written in the USA in the 1990s and published by Manna Publications (UK) since the year 2000 [1].
