John Montroll pioneered modern origami with the publication of his first book, Origami for the Enthusiast; Dover Publications, 1980, which was the first origami book where each model is folded from single square sheet and no cuts.
In the same book he also introduced the origami term "double rabbit ear fold".
He published at least 24 origami books. He is recognized for the exceptional clearness of his diagrams which makes its models accessible to greatest number.
I recommend his books for all beginners in origami. The folders who love complex should also know his models which propose beautiful, elegant and innovating folding sequences.
