Étienne Bazeries
Étienne Bazeries (21 August 1846, in Port Vendres – 7 November 1931, in Noyon) was a French military cryptanalyst active between 1890 and the World War I, First World War. He is best known for developing the "Bazeries Cylinder", an improved version of Thomas Jefferson's cipher cylinder. It was later refined into the US Army M-94 cipher device. Historian David Kahn (writer), David Kahn describes him as "''the great pragmatist of cryptology. His theoretical contributions are negligible, but he was one of the greatest natural cryptanalysts the science has seen.''" (Kahn 1996, p244) Bazeries was born in Port-Vendres, France, the son of a mounted policeman. In 1863 he enlisted in the army, and fought in the Franco-Prussian War, where he was taken prisoner of war, prisoner, although he later managed to escape disguised as a bricklayer. In 1874 he was promoted to lieutenant, and sent to Algeria in 1875. He returned to France the following year and married Marie-Louise-Elodie Berthon, ...

Port Vendres
Port-Vendres (; ; ) is a Communes of France, commune in the Pyrénées-Orientales Departments of France, department, southeastern France. A typical Mediterranean Sea, Mediterranean fishing port, situated near the Spanish border on the Côte Vermeille in southeastern France, Port-Vendres is renowned for its numerous fish and sea food restaurants. Geography Port-Vendres is located in the canton of La Côte Vermeille and in the arrondissement of Céret. Port-Vendres is one of the few deep-water ports in this part of the French Mediterranean coast. It takes freighters and cruise ships, as well as large and small fishing boats which may be seen arriving with their daily catch. The geomorphology of Port-Vendres meant that it developed in a different way from the nearby port of Collioure. Whereas Collioure has two beaches which slowly descend into a relatively shallow sandy-bottomed harbour, Port-Vendres is deeper and rockier. Collioure and Port-Vendres have therefore been used for ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

19th-century Cryptographers
The 19th century began on 1 January 1801 (represented by the Roman numerals MDCCCI), and ended on 31 December 1900 (MCM). It was the 9th century of the 2nd millennium. It was characterized by vast social upheaval. Slavery was abolished in much of Europe and the Americas. The First Industrial Revolution, though it began in the late 18th century, expanded beyond its British homeland for the first time during the 19th century, particularly remaking the economies and societies of the Low Countries, France, the Rhineland, Northern Italy, and the Northeastern United States. A few decades later, the Second Industrial Revolution led to ever more massive urbanization and much higher levels of productivity, profit, and prosperity, a pattern that continued into the 20th century. The Catholic Church, in response to the growing influence and power of modernism, secularism and materialism, formed the First Vatican Council in the late 19th century to deal with such problems and confirm cer ...

Rosario Candela
Rosario Candela (March 7, 1890 – October 3, 1953) was an Italian American architect who achieved renown through his apartment building designs in New York City, primarily during the boom years of the 1920s. He is credited with defining the city's characteristic terraced setbacks and signature penthouses. Over time, Candela's buildings have become some of New York's most coveted addresses. As architectural historian Cristopher Gray has written: "Rosario Candela has replaced Stanford White as the real estate brokers' name-drop of choice. Nowadays, to own a 10- to 20-room apartment in a Candela-designed building is to accede to architectural as well as social cynosure." Life Early life and education Born in Montelepre, Italy in 1890, Candela immigrated to New York in 1906. He returned to Italy after his arrival to study there and returned to the US in 1909. His father was Michele Candela, a plasterer, and his mother was Josephine Pizzurro. He gained admission to the Columbia ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cryptography
Cryptography, or cryptology (from "hidden, secret"; and ''graphein'', "to write", or ''-logy, -logia'', "study", respectively), is the practice and study of techniques for secure communication in the presence of Adversary (cryptography), adversarial behavior. More generally, cryptography is about constructing and analyzing Communication protocol, protocols that prevent third parties or the public from reading private messages. Modern cryptography exists at the intersection of the disciplines of mathematics, computer science, information security, electrical engineering, digital signal processing, physics, and others. Core concepts related to information security (confidentiality, data confidentiality, data integrity, authentication, and non-repudiation) are also central to cryptography. Practical applications of cryptography include electronic commerce, Smart card#EMV, chip-based payment cards, digital currencies, password, computer passwords, and military communications. ...

Man In The Iron Mask
The Man in the Iron Mask (; died 19 November 1703) was an unidentified prisoner of state during the reign of Louis XIV of France (1643–1715). The strict measures taken to keep his imprisonment secret resulted in a long-lasting legend about his identity. Warranted for arrest on 19 July 1669 under the name of "Eustache Dauger", he was apprehended near Calais on 28 July, incarcerated on 24 August, and held for 34 years in the custody of the same jailer, , in four successive French prisons, including the Bastille. When he died there on 19 November 1703, his inhumation certificate bore the name of "Marchioly", leading several historians to conclude the prisoner was Italian diplomat Ercole Antonio Mattioli. His true identity remains a mystery, even though it has been extensively debated by historians, and various theories have been expounded in numerous books, articles, poems, plays, and films. During his lifetime, it was rumoured that he was a Marshal of France or a President o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rossignols
The Rossignols, a family of French cryptographers and cryptanalysts, included Antoine Rossignol (1600–1682), Bonaventure Rossignol and Antoine-Bonaventure Rossignol. The family name means "nightingale" in French. As early as 1406, the word ''rossignol'' has served as the French term for "skeleton key" or for any tool which opens that which is locked. Antoine Rossignol In 1626, Henri II of Bourbon, Prince de Condé laid siege to the Huguenot city of Réalmont. The besiegers intercepted a coded letter leaving the city. Rossignol, then a 26-year-old mathematician, had a local reputation for his interest in cryptography. He quickly broke the Huguenot cipher, revealing a plea to their allies for ammunition to replenish the city's almost exhausted supplies. The next day, the besiegers presented the clear text of the message to the commander of Réalmont, along with a demand for surrender. The Huguenots surrendered immediately. This brought Rossignol to the attention of Louis XI ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Great Cipher
The Great Cipher (French: ''Grand chiffre'') was a nomenclator cipher developed by the Rossignols, several generations of whom served the French monarchs as cryptographers. The Great Cipher was so named because of its excellence and because it was reputed to be unbreakable. Modified forms were in use by the French Peninsular army until the summer of 1811. After it fell out of current use, many documents in the French archives were unreadable until it was decoded. Historical background Antoine Rossignol's cryptographic skills became known in 1626, when an encrypted letter was taken from a messenger leaving the city of Réalmont, controlled by the Huguenots and surrounded by the French army. The letter stated that the Huguenots would not be able to hold on to the city for much longer, and by the end of the day, Rossignol had successfully deciphered it. The French returned the letter with the deciphered message and forced the Huguenots to surrender. He and his son, Bonaventure Ros ...
