Another player in the story of Einstein and his copy of SD, is Laudahn who brought the Jack Brown’s article in Ojai Valley News to the attention of John Algeo. It is not clear if Laudahn is still alive and if he is, may be he can help identify Jack Brown. Her is an excerpt from an article I found in the cyberspace.
“Mr. Laudahn …. . Retired since 1976 and currently a resident of the Theosophical community of Taormina adjacent to the Krotona Institute in Ojai, California, Mr. Laudahn joined the T.S. (Adyar) in 1972 after having been associated with the United Lodge of Theosophists and the Theosophical Society (Pasadena). He is married to Gertrude Mann, herself a member of the T.S. (Adyar) since 1924.”
Anyone who is familiar with the theosophical men and women in Ojai valley who can throw some light on Jack Brown will be very helpful.
