The Witnesses of Jehovah constitute one of the most vigorous and spectacular religious propagandist bodies of the present day. Throughout the world an army of persistent enthusiasts tramp from door to door, urging people to adopt their teachings as a matter of life and death. They claim to have made over a million converts in recent years, chiefly in America; and they have been written up in the "Saturday Evening Post", "Collier's Weekly" and the "Reader's Digest" as a phenomenon of both national and international importance. This new sect originated in the U.S.A., to which the world owes Mormonism, Christian Science, Seventh Day Adventists, Father Divine, and so many other strange religious outbreaks. Charles Taze Russell, a draper of Pittsburgh, afterwards known as "Pastor" Russell, was the founder of the movement in 1872. Nathan Homer Knorr, its present head, prefers to say, "We broke in on the history of Jehovah's Witnesses" in 1872. And that leads us to the question of names.
