His birth date is mentioned in a 1973 book, "Leaders In American Education," in the UNI Library. There's also a book in that library that's co-authored by his daughter Linda, a marine biologist.
That language, named "aUI" in its own terminology, seems to be one of the most straightforward attempts to create a language in which the words directly refer to the essence of things. This language served the inventor Dr. John W. Weilgart as a successful tool in psychotherapy.
As I remember, Dr. Weilgart also believed that aUI might be used to communicate with whatever intelligent life might exist in Outer Space. He once showed me his correspondence with space pioneer Werner Von Braun, on that subject.
His interest in that subject had some slight similarity with that of Percival Lowell, an astronomer whose birthday will be March 13. Lowell correctly predicted the existence of the planet Pluto. However, he apparently made a big mistake, in thinking that life might have existed on Mars. Around 1956, he wrote a book, titled, "Mars, The New Frontier."
"The New Frontier" became a name of the Kennedy Administration, which emphasized space exploration, one objective of which was to land on the moon.
The following is from the Internet:
The therapeutic value of aUI lies within its simplicity. The user of this language is forced to express thoughts and feelings in a direct and very distinguished way. As an example, the English word “love” is translated into aUI as “brO” (together-good-feeling or together-joy), a letter is a “send-thoughts” and a photograph is a “light-picture”.
The Language of Space is the cosmic communication, whose elements can be learned in an hour. It is the primeval language of the Logos of pure reason that takes our human race back before the confusion of Tongues at the Tower of Babel.

Leibniz proposed a language to consist of categories. “aUI” contains “Ursprache” categories like Jung’s collective subconscious of creativity.
As the symbols (Ur-Gebärden, arche-gestures) are based on associations of meaning, the Language of Space is meaningful throughout, and thus quickly learnable even for people with little mechanic word-memory.
