Found another source in this newspaper (P3 bottom right)
https://www.coloradohistoricnewspapers.org/?a=d&d=CNK19691127-01.2.8&e=-------en-20--1--img-txIN%7ctxCO%7ctxTA--------0------These seem like pretty dubious publications to me... I'd call them "rags"
As for the people they refer to ...
Professor LJ Wilcox - University of ColoradoNo person by the name of LJ Wilcox has ever been a member of the academic staff at the University of Colorado. The closest I can find name-wise is Dr Laura J Wilcox, an Associate Professor in the Department of Meteorology at University of Reading on the UK... far too young to be writing anything in 1969
https://people.ncas.ac.uk/people/view/273Dr MR Kotowesky - Lick ObservatoryNo person by the name of "Kotowsky" with any initials has ever worked at, or been associated with, the Lick Observatory. In fact Lick Observatory astronomers collaborated with NASA in 1969 on the well known Lunar Laser Ranging Experiment. The experiment was coordinated by Joseph Wampler, now a professor emeritus. Difficult to believe that one of the staff would have called Apollo into question given Lick's active involvement.
Professor H Bundel- Belgian Academy of ScienceNo such professor exists in Belgium... no papers published. The nearest I have been able to find anywhere is Professor Himanshi Bundel, a Pharmacist at the Department of Medical Health, and Assistant Professor at the Katta College of Pharmacy in Kota, Rajasthan
https://www.signalhire.com/profiles/himanshi-bundel/217945144There is also no such institution as the
"Belgian Academy of Science". There is a something called the
"Royal Academies for Science and the Arts of Belgium (RASAB)", an umbrella organization for promoting science and arts in the country.
Professor SS Alpert - University of Sidney[sic]There is no record of a Professor SS Alpert publishing any papers, or being on the academic staff at the University of Sidney [sic], Australia
International Institute for Space StudiesNo such organization exists, or has ever existed, and certainly not in Berne, Switzerland. There are the following similarly named organzations
The International Space Science Institute (ISSI) located in Berne and founded in 1995
The International Institute for Space Studies and Research (IISSR)", located in Telangana, India, and founded 1989.
Space Studies Institute (SSI): Founded in 1977 by physicist Gerard K. O'Neill.
International Academy of Space Studies (IASS): A non-profit association founded in Brazil in 2021.
None of them existed in 1969
Conclusion.1. The claimed people referenced in the historical article don't exist.
2, With the exception of the Lick Observatory, The University of Sydney (misspelled as Sidney) and the University of Colorado, none of the other claimed organizations exist.
3. The similarly named organizations do exist, but they did not exist in 1969.
Therefore, the historical articles were bullshit back then, and they are still bullshit to this day.
