Russell moved the Watch Tower Society's headquarters to Brooklyn, New York, in 1909, combining printing and corporate offices with a house of worship; volunteers were housed in a nearby residence he named Bethel. He identified the religious movement as "Bible Students," and more formally as the International Bible Students Association. By 1910, about 50,000 people worldwide were associated with the movement and congregations re-elected him annually as their "pastor." Russell died October 31, 1916, at the age of 64 while returning from a ministerial speaking tour.
