Hi author! Given the timeframe of the subject, I was surprised to see no mention in the New Yorker article of Al Hubbard, who was well known to be involved in that early era, both in developing now common therapeutic practices such as the use of the Hubbard Room, and working to expose as many influential cultural, religious, industrial, government, and military figures to the experience as possible.

Was there any collaboration or correspondence between Mead/Bateson and Hubbard? Documentation on Hubbard can be hard to find, and he seems to have preferred it that way.
