Lt Norman Percy Grubb (1895-1993) was born in London, the son of an Irish ordained minister. Norman served in the Gloucester Regiment during WWI. In 1919 he married CT Studd's daughter Pauline, and joined their young WEC mission in the Congo, where he earned the name 'Rubi'.
During his time as the General Secretary of WEC, Grubb began writing. He first produced tracts and magazines for the mission, and then in 1933 he published a biography of his father-in-law: CT Studd: Cricketer & Pioneer. After this came a string of other books, including his autobiography Once Caught, No Escape, and the pamphlet The Key to Everything.
Other books penned by Grubb include Continuous Revival, Touching the Invisible, Rees Howells Intercessor, Law of Faith, The Liberating Secret, The Deep Things of God, God Unlimited, Spontaneous You, Who Am I?, and the controversial Yes I Am.
Several of these titles have been republished by Zerubbabel Press, Amazon, Barnes & Noble.
