Early life and career
Olcott was born in Orange, New Jersey, in 1832 into a Presbyterian family. As a young man he studied scientific agriculture, helped run a model farm and wrote on farming, serving as agricultural editor of the New York Tribune around 1858-1860. During the American Civil War he served in the Union army and was appointed a special commissioner of the War Department in New York, investigating fraud and corruption among military contractors, work that earned him the rank of colonel. In 1865 he assisted in the investigation of the assassination of Abraham Lincoln. After the war he practiced law in New York.
Like many Americans of his generation, Olcott was drawn to Spiritualism. In 1874, while reporting for a New York newspaper on seance phenomena at the Eddy family farm in Chittenden, Vermont, he met the Russian-born Helena Petrovna Blavatsky. His reports were collected in People from the Other World (1875), and the meeting changed the course of his life.
Founding the Theosophical Society
In September 1875, at a gathering in Blavatsky's New York rooms, Olcott, Blavatsky, William Quan Judge and others agreed to found a society for the study of occult and esoteric subjects. The Theosophical Society was formally organized that autumn, and Olcott became its president, a post he held for more than three decades. His inaugural address in November 1875 is often taken as the society's founding moment.
Olcott was the organizer and administrator of the movement, while Blavatsky was its teacher and writer. In 1878 the two left for India, arriving in Bombay early in 1879, and in 1882 they established the international headquarters at Adyar, near Madras, where it remains today. Olcott also founded and edited the society's journal The Theosophist.
Buddhism and the revival in Sri Lanka
In May 1880 Olcott and Blavatsky visited Ceylon, now Sri Lanka, where they formally took the refuges and the Five Precepts from a Buddhist monk, becoming among the first Westerners publicly to embrace Buddhism. At that time Buddhist education on the island was weak compared with Christian mission schools. Olcott worked with Sinhalese Buddhist leaders to found Buddhist schools, including Ananda College in Colombo, and the Buddhist Theosophical Society helped establish hundreds of schools in the following decades.
His Buddhist Catechism (1881), a question-and-answer summary of Buddhist teaching approved by leading monks, was translated into many languages and is still used in Sri Lanka. He campaigned for Buddhist civil rights under British rule, helped secure recognition of Vesak as a public holiday, and advised the committee that designed the Buddhist flag in 1885, later adopted internationally. He also influenced the young Anagarika Dharmapala, who became a major Buddhist reformer.
Later years and controversies
Olcott's presidency saw the society's greatest growth and its first crises. In 1885 a report for the Society for Psychical Research, written by Richard Hodgson, accused Blavatsky of producing fraudulent phenomena at Adyar; defenders disputed its methods, and the controversy continues among historians. After Blavatsky's death in 1891, tensions with Judge led the American section to break away in 1895. Olcott remained president of the Adyar society until his death at Adyar in 1907, and Annie Besant succeeded him.
His six-volume memoir Old Diary Leaves, published serially and in book form from 1895 onward, is a key, if partisan, source for the early history of Theosophy.
Legacy
Olcott is remembered very differently in different places. In Sri Lanka he is honored as a benefactor of Buddhist education, with streets and schools named after him and commemorations on the anniversary of his death. Scholars of religion see him as an early example of "Protestant Buddhism," a modernized, text-centered presentation of Buddhism shaped partly by Western categories. In the history of Western esotericism he stands as the practical builder behind the Theosophical movement, which later influenced Anthroposophy, modern Buddhism in the West and the wider interest in Asian religions.
Biographers such as Stephen Prothero have portrayed him as a creative, if sometimes naive, intermediary between American Protestant culture and Asian religions. His career shows how a practical reformer with little formal training in Asian languages could nonetheless reshape the public face of a religion far from his birthplace.
