Throughout his childhood, Izzy Posen was a bright boy with a curious mind. At school, he worked hard, with long hours of study stretching late into the evenings. He was a shining example to his nine younger siblings.
But at his unregistered school in the heart of the Haredi, or ultra-Orthodox Jewish, community in Stamford Hill in north London, and later at a yeshiva, or religious school, in Gateshead, Posen was taught only in Yiddish and studied only religious texts. No maths, no English, no history, no science.
