Henry Steel Olcott
The Theosophical Society was officially formed in New York City on 17 November 1875 by Helena Blavatsky, Henry Steel Olcott, William Quan Judge, and others. It was self-described as "an unsectarian body of seekers after Truth, who endeavour to promote Brotherhood and strive to serve humanity". After a few years Olcott and Blavatsky moved to India and established the International Headquarters at Adyar, in Madras.
