I was an undergrad CS intern (and Chaos enthusiast) assisting the physicists at Los Alamos Natl. Labs Center for Nonlinear Studies when he visited to give the monthly “Tea Talk” on some subject in nonlinear mathematics/ chaos theory back in ‘88. I didn’t understand most of what he said. I asked the Deputy Director, a long-time PhD Theoretical Physicist, about the gist of the talk afterwards. He said “I didn’t understand most of what he said. Maybe if I had been collaborating with him for a few months...”

Feigenbaum was a fascinating man and some of his writing is what made me want to get an internship at the Center. I never dreamed I meet the man over tea.

A great man.
