John Montroll is an American master origami artist and prolific author, well known by paper-folding enthusiasts throughout the world.

## Biography

John Montroll was born in Washington, D.C.[1] He is the son of Elliott Waters Montroll, an American scientist and mathematician.

Montroll mastered his first origami book, Honda's How to make Origami, at the age of six,[1] the same age he began creating his own origami animals.[2] He became a member of the Origami Center of America at age twelve.[1] He attended his first origami convention at age 14. Montroll now teaches mathematics at St. Anselm's Abbey School in Washington, D.C, teaching small groups of advanced math students, AB and BC Calculus, and is most famous there for his invention of the Montroll Method for determining the inverse of a given figure on a 2-dimensional plane, especially waterfowl and most notably ducks.This is a result of his unique teaching method in which he distributes materials in a form he designates "packets". These packets are often intentionally vague to put the responsibility of learning on the student, thus reinforcing what he learns. He even teaches an Origami class. One of John Montroll's hobbies is whistling [1]. He can whistle in 5 octaves, and has shown this talent at 2 Whistling conventions in Louisburg, North Carolina.

John Montroll pioneered modern origami with the publication of his first book, Origami for the Enthusiast; Dover Publications, 1979, which was the first origami book where each model is folded from single square sheet and no cuts.[citation needed] In the same book he also introduced the origami term "double rabbit ear fold".

## The Montroll Method

The Montroll Method is a patent pending, 3 step style of teaching created by John Montroll. This method has been widely considered as highly controversial, and has been cited as one of the causes for the Afghan war[citation needed].

The first step is to reinforce positive behavior, and negate negative behavior. Montroll personally achieves this by telling his students and underlings to "Be Good."

The second step is teaching via vague material as this reinforces the students ability to use their cognitive reasoning to solve problems. While this can range greatly, Montroll's preferred teaching style is packets, especially purposely ambiguous packets of homework questions that are designed to take anywhere from 30 seconds to 3 hours. If a students have any questions regarding these packets, he tends to refer the students back to step one.

The final step is to draw a duck.
