Joseph Sieber Benner (January 3, 1872 – September 24, 1938) was an American author, New Thought writer and Representative of the Brotherhood of Christ who used the pen name "Anonymous". He was the first to introduce the Knowledge and Teachings of Impersonal Life (also known as the "I AM" Teaching) to the world in his first book, The Impersonal Life published in 1914. His other works were The Way Out, The Way Beyond, Wealth, Teacher, Brotherhood, The Way to the Kingdom, Papers (65 Lessons), etc.

According to author Jon Klimo, "by 1916, Benner said he felt he could no longer resist the growing inclination to give himself over as a vehicle to a larger presence, to let his mind be subsumed by (or co-creatively interact with) a larger Mind or Being." His book The Impersonal Life contained words Benner believed were recorded directly from God, and was first published in July 1914. Benner taught that Christ's proclaiming "I AM" indicated "the true spirit that resides in every human being." The "SUN center" was an Ohio group formed in 1920 around Benner's teachings. One of the group's practices was to "enter into the silence, stillness and peace" each day at noon. Benner also made a series of lessons called the "Inner Life Courses" he intended to develop discipline in life, discernment and the awakening of the Christ within the soul.

Benner died in 1938. According to his daughter, letters were found after his death in which he expressed devotion to God and his belief that God had chosen him as a medium.

In the 1960s Elvis Presley was introduced to Benner's work by his hairdresser-turned-guru, Larry Geller. In the last 13 years of his life, Presley gave away hundreds of copies of the book. A copy was allegedly with him on the night he died. (wikipedia.org)
