This month, Jean Dubuis, founder of The Philosophers of Nature, and it's French progenitor, passed away April 6th 2010.
I never had a chance to learn directly from the man, but his students have presented some of the easiest to understand works on modern laboratory alchemy that I have ever read. His courses have been entrusted to Triad Publishing for posterity, and can be purchased there.
I only know him from his writings, and from them he seemed a very wise and down to earth man who distrusted unnecessary secrecy, and found it downright harmful. For that alone I would have liked the man.
Rest in Peace Jean. You left the world better than when you got it. For that I'm grateful. Thank you.
