Charles Taze Russell (February 16, 1852 – October 31, 1916), or Pastor Russell, was an American Adventist minister from Pittsburgh, Pennsylvania, and founder of the Bible Student movement. He was an early Christian Zionist.
In July 1879, Russell began publishing a monthly religious magazine, Zion's Watch Tower and Herald of Christ's Presence. In 1881, he co-founded Zion's Watch Tower Tract Society with William Henry Conley as president. In 1884 the corporation was registered, with Russell as president. Russell wrote many articles, books, tracts, pamphlets and sermons, totaling approximately 50,000 pages. From 1886 to 1904, he published a six-volume Bible study series titled Millennial Dawn, later renamed Studies in the Scriptures, nearly 20 million copies of which were printed and distributed around the world in several languages during his lifetime.
