aUI (capitalization significant) was created in the 1950s by John Weilgart, an Austrian-born psychiatrist working in Iowa. (We can discount the story that he learned it in an instant from a little green man when he was a child of 5 on internal evidence alone: the precise fit with the English alphabet - including some pushing to make the fit -- the frequent coincidences of aUI and English or German words, the rigorous SAE grammar, and so on for quite a while). He publishedaUI The Language of Space first in 1961 and continued working on it until at least 1979, when he published the 4th revised and expanded edition, with the further subtitle Pentecostal Logos of Love & Peace. The basic language changed little over the years, the new books added new ways to approach the topic, new stories (apparently autobiographical, but probably not -- see above), and new commendation from various scientific and "scientific" sources. There seems to have been an occasional flurry of interest in aUI: a now defunct list, a commercial site (also defunct) for Cosmic Communication Co. (run by a daughter?) and a recent Facebook family with a handful of active members.
