The MIT link I shared mentioned Demaine studied Huffman's work but the mini and full paper make no reference. I first heard about this from Huffman when Demaine was about 16 years old. So I would hope for some reference there in.
If you like the Demaines' work, you'll probably like the award-winning PBS documentary Between The Folds [0] which features them and many other amazing people working with origami.
Every time something like this comes up, I recall “office hours” with David Huffman at UC Santa Cruz. Most of the conversation was about things other than class. One frequent topic was his paper folding.
