The Theosophical Society in America is a section of the worldwide Theosophical Society founded in New York in 1875 with its international headquarters at Adyar, Chennai (Madras), India. The American section has its national center in Wheaton, Illinois, on a beautiful estate called Olcott in honor of the American cofounder and first President of the Society, Colonel Henry Steel Olcott.
Olcott is the administrative headquarters of the Theosophical Society in America, but it is also a place where members and the public may participate in onsite courses, workshops, and retreats, or attend lectures and seminars on a wide variety of spiritual topics. It provides a summer convention for members in conjunction with the Society’s Annual Meeting, usually in July, at which prominent Theosophical students gather to learn from one another. A number of these programs have been recorded and are posted online for free viewing or listening (See the Online Resources menu).
