Jonathan Crabtree was born 24 April 1961 in Melbourne Australia.

In 1983, while studying at Melbourne University, he broke his spine in a motorcycle accident. Upon admission to the emergency department of the Alfred Hospital he was advised that if he moved, he'd never walk again.

To control his pain, Jonathan used various breathing and visualisation techniques and promised to make mathematics simpler if he could walk again.

Upon regaining his health he completed a Bachelor of Commerce Degree and commenced work with a management consultancy called IBIS.

IN 1987 Crabtree quit his job to become a mathematics tutor. Today, he write articles on the topic of the lost logic of elementary mathematics and maintains a website at http://www.jonathancrabtree.com/mathematics
