The initial years of the Bible Investigators (Jehovah’s Witnesses) are the merit of their founder, Charles Taze Russell. Of a little research group he made the organization which covers many countries on all continents. He propagated his ideas by the editorialpropagandist corporation, named Zion’s Watch Tower Tract Society, which he established and became its president. Many missionary travels of Russel and his followers, especially the four-month Evangelic travel around the World, led to a dynamic growth of the organization, what is proved with offices in several countries and hundred thousands followers and sympathizers of this religious movement. In the year 1914 the organization suffered form its first serious crisis caused by the undone prophecy of the end of world’s system and the presence of Christ in the world. However, in spite of the crisis and resignation of many members, the organization survived.
