National Center

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 co-founder 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, retreats, lectures, and seminars on a wide variety of spiritual topics. It is a busy center and a beautiful place, providing a focal point for the energies and efforts of members throughout the American Section.

Olcott is also a symbol of the aspiration and the commitment that brought it into being and that continue to sustain it as a place of wise inspiration, strength, and beauty.

The staff at Olcott consists of approximately fifty employees who carry on the work of the national center, all of whom are dedicated to the unique work of the Theosophical Society in America.

The Theosophical Society's campus buildings are wheelchair accessible.

For the first fifty years of its history, the Society had its headquarters in various locations, according to the residence of its national presidents. In the mid 1920s, while L. W. Rogers was president of the American Section, the Wheaton site was selected. The property was purchased and continues to be maintained through the dues and gifts of members. In 1926 the cornerstone of the main building was laid by Annie Besant, second international President of the Society. This building was first occupied in 1927, and since that time has continued as the center of Theosophical work in the United States.
