Len Kasten has a B.A. degree from Cornell University, where he majored in psychology and minored in literature and philosophy. After graduating from Cornell he entered the U.S. Air Force Aviation Cadet program. While in the Air Force he experienced a UFO encounter that had a transformative effect on his life, although he didn't realize it until a few years later. After serving in the Air Force he moved to Richmond, Virginia. On frequent trips to Virginia Beach, he spent a lot of time in the extensive New Age library at the Association for Research and Enlightenment (A.R.E.), the organization founded by psychic Edgar Cayce, where he acquired a self-education in metaphysics. He then moved to Boston where he was introduced to Theosophy and joined the Boston Theosophical Society. At that time, the BTS was the central meeting place for a variety of New Age personalities who later achieved notoriety, including yoga guru Marcia Moore, the subject of the classic book Yoga, Youth and Reincarnation by Jess Stearn, Louis Acker, co-author with Frances Sakoian of The Astrologer's Handbook , which has to-date sold hundreds of thousands of copies, and Isabel Hickey, author of Astrology: A Cosmic Science , who went on to become recognized as one of America's foremost astrologers.
Then later, while working in Washington D.C. in the 1960s, he felt drawn to join the National Investigations Committee on Aerial Phenomena (NICAP). NICAP was the most prestigious organization in the country investigating UFO phenomena. At that time, in the mid-1960s, there was a wave of UFO sightings all across the country, and NICAP was precisely in the eye of the storm. It was swamped with inquiries from the public and the media, and was the major source of information nationally for UFO reports. Thanks to its thorough, careful field investigation program, NICAP was able to provide solid evidence to the press, which had the effect of embarrassing the government into beginning its own serious UFO investigation – the now infamous Project Blue Book. Len then moved to Hartford, Connecticut where he joined the American Philosopher Society. Upon the death of the founder, Cyril Benton, Len became the president of the society. In the 1980s, the APS, under Len's leadership, commenced a program of weekly public lectures by prominent metaphysical and ufology researchers, writers, and leaders. Over a ten year period, some of the most fascinating New Age personalities in the East appeared at the APS in Wethersfield, Connecticut, including Bernie Siegal, Kenneth Ring, Larry Warren, John White, Swami Satchidananda, Viktoras Kulvinskas, Larry Fawcett, and Betty Andreasson Luca. At one unforgettable meeting, the audience was instructed in mental spoon bending, a la Uri Geller, resulting in a lot of twisted dinnerware. And it was at the APS where Larry Warren first publicly told his story about his role in the now-famous UFO incident at RAF Bentwaters in the UK in 1980, later to become the subject of the book Left at East Gate by Larry Warren and Peter Robbins. In that ten year period, the APS brought over four-hundred speakers to public attention, many later to become well-known.
While living in Connecticut Len became the editor of an early New Age publication, Metamorphosis Magazine co-founded with Gordon-Michael Scallion, who has since become well-known as the founder of the Matrix Institute and author of Notes from the Cosmos , and then he became the editor of Horizons Magazine . In 1995, back in Washington and active in the UFO disclosure movement, Len participated in the public protest at the Government Accounting Office for the release of the Roswell files. In 1996, again living in Richmond, Virginia, Len began writing feature articles for Atlantis Rising Magazine . By this time, deeply involved in UFO research, most of his articles for the magazine were UFO related, although he also wrote about life after death, sacred geometry, Atlantis, free energy, holistic health, and other New Age subjects, much of his knowledge gleaned from his days at the A.R.E. library, his Theosophical studies, and from the store of knowledge of his APS associates and presenters. By 2010, Len had written fifty-two articles for Atlantis Rising , including eight cover stories. Over that fourteen year period, Len attended the annual week-long UFO Congress in Laughlin, Nevada, where he met and attended the lectures of hundreds of UFO investigators, researchers and writers from all over the world, several of whom he interviewed for Atlantis Rising.
It is now generally recognized that understanding the UFO/ET phenomena requires knowledge of metaphysics as well as analysis of the evidence. Since Len was able to bring his extensive metaphysical background into the writing of The Secret History of Extraterrestrials , the book achieves a depth of understanding of the phenomena not otherwise possible.
