Charles Taze Russell , also known as Pastor Russell, was a Protestant evangelist from Pittsburgh, Pennsylvania, USA and founder of the Bible Student movement.

After having published several articles in various religious journals as early as 1876 he formed his own religious journal Zion's Watch Tower and Herald of Christ's Presence in 1879, as well as establishing Zion's Watch Tower Tract Society in 1881. In 1884 Zion's Watch Tower Tract Society published the first in a series of seven books entitled Studies in the Scriptures with the first six originally entitled The Millennial Dawn. In 1908 Russell transferred the headquarters of the Society to its current location in Brooklyn, New York.
