His employer Shell Oil Company tried unsuccessfully to censor him. They requested he not give his important presentation at some forum.
one of my former thesis advisors from a number of decades ago worked with King Hubbert at the Shell research centre. He was and still is actually quite well known for the same bit of research Hubbert was really famous for...pore fluid pressure and it's impact on deformation. Few people here realize that Hubbert was first and foremost a rock mechanics scientist and his papers with Rubey are still de rigeur reading for anyone trying to understand this subject, my own MSc thesis was littered with references to Hubbert, Hubbert and Rubey and Rubey and Hubbert. His foray into peak oil and other subjects (technocracy) was a bit of a sideline for him...a brilliant mind who loved to question everything and wasn't afraid of controversy. One of my other thesis advisors (God rest his soul) was at the AAPG conference when Hubbert first brought forward the idea the US was running out of oil. When he relayed this story to me it was by then quite apparent that Hubbert was right but he said back when the talk was given pretty much everyone walked out of the talk shaking their head and thinking he had lost his mind. And that would have been a group of the penultimate oil explorers of that generation ...Halbouty, Hedberg, etc. According to my former thesis advisor everyone who worked for him thought he was brilliant...but a bit of a nutter.
If you are looking for quotes from folks who worked under Hubberts direction at Shells research labs a number of them are professor emeritus at Texas A&Am or completely retired by now. John Handin I believe was one, Peter Gretener another, I think Mel Friedman as well (and a number of names I can't remember right now). These gentlemen wrote the book on rock mechanics...literally.
