Charles Taze Russell (February 16, 1852 October 31, 1916), or Pastor Russell, was a prominent early 20th century Christian Restorationist minister from Pittsburgh, Pennsylvania, USA and founder of what is now known as the Bible Student movement, from which Jehovah's Witnesses and numerous independent Bible Student groups emerged. Beginning in July, 1879 he began publishing a monthly religious journal Zion's Watch Tower and Herald of Christ's Presence. The magazine is now published semi-monthly under the name, The Watchtower Announcing Jehovah's Kingdom. In 1881, he co-founded Zion's Watch Tower Tract Society and in 1884 the corporation was officially registered, with Russell as president. Russell was a prolific writer, producing many articles, books, pamphlets and sermons, totalling 50,000 printed pages, with almost 20 million copies of his books printed and distributed around the world.[2] From 1886 to 1904, he published a six-part series entitled The Millennial Dawn, which later became known as Studies in the Scriptures.
