The city of Poznan was, with an eight-year hiatus in the Napoleonic period, in Prussia from 1793 to 1919. It was the birthplace of Paul Saladin Leonhardt (1877 to 1934).

After graduating, this gifted student enrolled in the University of Leipzig. He studied modern languages, but the charm of the sixty-four squares exerted a greater attraction on him than his studies. Leonhardt soon rose to become the champion of the Leipzig Chess Club "Augustea"; and he then devoted himself entirely to chess as a professional player and also a journalist. In 1903 he won the masters tournament in Hilversum.

Before the war he was one of the best German chess players. His victory in the in 1907 Copenhagen international tournament ahead of Maróczy and Schlechter underlines this. During the Weimar Republic, Leonhardt carved out a career as a poet and political journalist.

Chess, however, served him throughout his life as a livelihood. His chess columns in the "Hamburger Nachrichten" and the "Konigsberg Allgemeine Zeitung" were well regarded for their very deep analysis. As a chess teacher, he produced radio programmes for Konigsberg radio which enjoyed large audiences.

It is not a "revisionist history". The biography does state the facts. While Her Leonhardt was born in Posen, Germany, and died in Koenigsberg, Germany, the geopolitical map of Europe has changed since then.

The additional info (Poznan and Kaliningrad) is for those who may try to look up Posen and/or Koenigsberg on the map of Germany. They would not find them.

Mr.Leonhardt certainly had Nimzo's number in their 1911. match. but it should be noted that the overall score between the two was in Nimzowitsch's favour:

+6 -5 =2.

Richard the Lionheart (properly, King Richard I of England: http://en.wikipedia.org/wiki/Richar...) and Saladin (formally Salah ad-Din Yusuf ibn Ayyub or "Righteousness of the Faith Joseph Son of Jacob": http://en.wikipedia.org/wiki/Saladin) were leaders of the respective Christian and Muslim forces in the Third Crusade.

Mr LEONHARDT Sr: [To his wife] Word up bee-yarch!! Have you thought of a name for the new child.

Mrs LEONHARDT: Yes. Paul.

Mr LEONHARDT Sr: What about a middle name? How about naming him after the most famous kurd in history?

Perhaps Volkswagen is not the most fortunate example to make this rhetorical point:

<... Adolf Hitler said of the Tatra 'this is the car for my roads'.[2][3] Ferdinand Porsche later admitted 'to have looked over Ledwinka's shoulders' while designing the Volkswagen.[2][4] In the same sentence he stated that Ledwinka sometimes looked over Porsche's shoulder.

Tatra sued Porsche for damages, and Porsche was willing to settle. However, Hitler canceled this, saying he 'would settle the matter.' [5] When Czechoslovakia was invaded by the Nazis, the production of the T97 was immediately halted, and the lawsuit dropped. After the war, Tatra reopened the lawsuit against Volkswagen. In 1965, the matter was settled when Volkswagen paid Tatra 1,000,000 Deutsche Mark in compensation.[6] >
