About the Author

Jakow Trachtenberg was a Jewish mathematician who developed the mental calculation techniques called the Trachtenberg system. He was born in Odessa, the Russian empire in 1888 and worked as an engineer in the Obukhov arms factory. He was a dedicated pacifist and instrumental in organising the Society of Good Samaritans when the First World War broke out. After the Russian revolutions of 1917, Trachtenberg fled to the Weimar Republic where he was later critical of Nazi policies and imprisoned in a concentration camp during World War II. He developed his system of mathematics during his imprisonment. He died in 1953.

Even in the age of the calculator this new ... edition is well worth reading and the challenge of teaching the method to children who find arithmetic difficult is one which an adventurous teacher might well find rewarding. -- John Dunford * The Mathematical Gazette *
