Here is an interesting Polish – American connection. Have you ever heard of the Voynich manuscript?
It is a very interesting, mysterious and beautiful book that was bought by Michał Wojnicz (Wilfrid Voynich) – a Polish dealer of antiquated books who originally came from Sułwałki but who settled in NYC. He operated one of the largest rare book businesses in the world at that time. Poles have an honorable history with breaking codes like with the Enigma during WW2, were Jerzy Rozycki, Henryk Zygalski and Marian Rejewski broke the German decipher which helped end the war. Despite Poles having a talent for solving such mysteries, neither Michał Wojnicz nor anyone else since his discovery has been able to decipher it. So I invite this generation of Poles to finish what Mr. Wojnicz started!
Below is a description of the book found in Wikipedia:
The Voynich manuscript is an illustrated codex hand-written in an unknown writing system. The vellum on which it is written has been carbon-dated to the early 15th century (1404–1438), and it may have been composed in Northern Italy during the Italian Renaissance.The manuscript is named after Wilfrid Voynich, a Polish book dealer who purchased it in 1912.
Some of the pages are missing, with around 240 remaining. The text is written from left to right, and most of the pages have illustrations or diagrams. Some pages are foldable sheets.
The Voynich manuscript has been studied by many professional and amateur cryptographers, including American and British codebreakers from both World War I and World War II. No one has yet succeeded in deciphering the text, and it has become a famous case in the history of cryptography. The mystery of the meaning and origin of the manuscript has excited the popular imagination, making the manuscript the subject of novels and speculation. None of the many hypotheses proposed over the last hundred years has yet been independently verified.
The world is full of mystery, go explore it like Michał Wojnicz did!!!
