Biography

He was born in Odessa, in the Russian Empire (today Ukraine). He graduated with highest honors from the Mining Engineering Institute in St. Petersburg and later worked as an engineer in the Obukhov arms factory. While still in his early twenties, he became Chief Engineer with 11,000 men under his supervision. The Tsarist government gave him the responsibility of supervising the formation of a well-developed navy.

After the Russian Revolutions of 1917, Trachtenberg fled to Weimar Republic where he became critical of Nazi policies. He was imprisoned in a Nazi concentration camp during World War II. He developed his system of mental arithmetic during his imprisonment. He later fled to Switzerland.
Early life

Trachtenberg was a dedicated pacifist. When war broke out in 1914, he was instrumental in organising a society known as the Society of Good Samaritans. The idea was to train Russian students to take care of the wounded. It also had a special recognition from Tsar Nicholas II. He was against violence of any sort despite having a leading position in tsarist arms production. He refused to accept defeat even under trying conditions.
Later life

In Switzerland, he started teaching his mental manipulation of numbers, and he became somewhat well-known. He was especially successful with children having problems with ordinary mathematical teaching.
