There he learnt classics, studying Latin for nine years and Greek for six years. The school also taught French but, as was usual at this time, not much science. Although very little mathematics was taught in German schools in general, Walter had the advantage that the Leibniz Gymnasium taught more mathematics than other schools as a mark of respect for Leibniz after whom the school was named.

In 1928, when he was seventeen years old, Ledermann graduated from the Leibniz Gymnasium and received the necessary certificate which allowed him to study at any German university. He remained in Berlin and entered the University there (now the Humboldt University) to study for the State Examination which was the qualification necessary to enter secondary school teaching. At the University of Berlin Ledermann was taught by many famous mathematicians including Schur Schmidt , von Mises Planck Hopf Feigl , and others.

Ledermann's St Andrews interview Scottish index History Topics Index We interviewed Walter Ledermann in St Andrews in September 2000. Part 1: Parents and upbringing EFR: Could you tell us something about your parents. My father was born in Berlin, although his father came from a part which is now Polish and he was originally a schoolteacher. Because in my father's school there were both Polish and German speaking children, my father was bilingual. I never met my grandfather because he died the year I was born. My parents, my father certainly, entirely felt himself to be German. He had a German name, and was born in Berlin. In the First World War he was called up as a doctor in the medical service, became a captain in the army, was sent to the front in Belgium and France, and so on. He was a very patriotic German, and whatever he saved as a doctor he bought German Government bonds to support the government. Then came hyperinflation in 1922 when money was completely wiped out. In the end, after one year, the new currency was introduced at the rate of 1 to 10 . One billion old marks was one new mark. Then my father got a letter from the bank where he had been saving his assets, saying, "Dear doctor we have, of course, all your savings, your Government bonds etc, and if you would be kind enough to come here and collect them, we will be at your disposal. But we cannot send them to you by post because their total value is less than the stamps ..."

EXPLANATION ''Typically, a canonical form can be specified by providing both the country and area code of the fax number. Thus, the number is the Canonical Form of the local call . The use of the Canonical Form is in batching of faxes. If two faxes are using a Class or Classes that allow batching, and the Canonical Form of the two faxes are the same, they would be batched together and sent in one call. This can reduce costs because many long distance carriers charge extra for the initial one minute or so. Also the time spent during the start of the call to initialize the fax machine is incurred only once.'' EXAMPLE The number is the Canonical Form of the local call
