Geneseo is a city in Henry County, Illinois, United States. As of the 2020 census, the population was 6,539. Geneseo is 20 miles east of the Quad Cities, at the intersection of Interstate 80, U.S. Route 6 and Illinois Route 82. Geneseo is well known for its Victorian-style architecture, quaint downtown, and its successful high school music and football programs. History Geneseo was founded as a Christian colony in 1836 by seven families of the Congregationalist denomination from Geneseo, New York and Bergen, New York seeking to establish a "church in the wilderness". Roderick R. Stewart, one of the city's founding members, named the town Geneseo after the settlers' town of origin in New York. The name "Geneseo" is a variation of the Iroquois word Genesee, meaning "shining valley" or "beautiful valley". Journey Planning for the colony began as early as 1829.

Japanese M-1 Cipher Machine
The Japanese M-1 cipher machine was a mechanical device the Japanese used for performing cryptography sometime during the 1930s. More specifically it was used by naval attaches. The US called it the ''ORANGE machine''. Cryptographically it is similar to the Red cipher; it was broken by Agnes Driscoll Agnes Meyer Driscoll (July 24, 1889 – September 16, 1971), known as "Miss Aggie" or "Madame X'", was an American cryptanalyst during both World War I and World War II and was known as “the first lady of naval cryptology."

Japanese Naval Codes
The vulnerability of Japanese naval codes and ciphers was crucial to the conduct of World War II, and had an important influence on foreign relations between Japan and the west in the years leading up to the war as well. Every Japanese code was eventually broken, and the intelligence gathered made possible such operations as the victorious American ambush of the Japanese Navy at Midway in 1942 (by breaking code JN-25b) and the shooting down of Japanese admiral Isoroku Yamamoto a year later in Operation Vengeance. The Imperial Japanese Navy (IJN) used many codes and ciphers. All of these cryptosystems were known differently by different organizations; the names listed below are those given by Western cryptanalytic operations. Red code The Red Book code was an IJN code book system used in World War I and after. It was called "Red Book" because the American photographs made of it were bound in red covers.Greg Goebel"US Codebreakers In The Shadow Of War" 2018. It should not be confu ...

Joseph Rochefort
Joseph John Rochefort (May 12, 1900 – July 20, 1976) was an American naval officer and cryptanalyst. He was a major figure in the United States Navy's cryptographic and intelligence operations from 1925 to 1946, particularly in the Battle of Midway. His contributions and those of his team were pivotal to victory in the Pacific War. Early career Rochefort was born in Dayton, Ohio. In 1917, he joined the United States Navy while still in high school in Los Angeles, without obtaining a diploma. He enlisted in the Navy in 1918, lying that he was born in 1898 so as to appear almost 21 and eligible for the service. This adjustment lasted his entire career. He was commissioned as an ensign after a 14 June 1919 graduation from the US Navy's Steam Engineering School at Stevens Institute of Technology, and later in 1919 became engineering officer of the tanker USS ''Cuyama''. A fellow officer observed that Rochefort had a penchant for solving crossword puzzles and adept skills at playi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Diplomatic Correspondence
Diplomatic correspondence is correspondence between one state and another and is usually of a formal character. It follows several widely observed customs and style in composition, substance, presentation, and delivery and can generally be categorized into letters and notes. Letters Letters are correspondence between head of state, heads of state, typically used for the appointment and recall of ambassadors; for the announcement of the Demise of the Crown, death of a sovereign or an accession to the throne; or for expressions of congratulations or condolence. Letters between two monarchs of equal rank will typically begin with the salutation "Sir My Brother" (or "Madame My Sister", in the case of a female monarch) and close with the valediction "Your Good Brother" (or Sister, in the case of a female monarch). In the case where one monarch is of inferior rank to the other (for instance, if the Grand Duke of Luxembourg were to correspond with the King of the United Kingdom), the inf ...

Herbert Yardley
Herbert Osborn Yardley (April 13, 1889 – August 7, 1958) was an American cryptologist. He founded and led the cryptographic organization the Black Chamber. Under Yardley, the cryptanalysts of The American Black Chamber broke Japanese diplomatic codes and were able to furnish American negotiators with significant information during the Washington Naval Conference of 1921–1922. Recipient of the Distinguished Service Medal. He wrote ''The American Black Chamber'' (1931) about his experiences there. He later helped the Nationalists in China (1938–1940) to break Japanese codes. Following his work in China, Yardley worked briefly for the Canadian government, helping it set up a cryptological section (Examination Unit) of the National Research Council of Canada from June to December 1941. Yardley was reportedly let go due to pressure either from the Secretary of War Henry L. Stimson or from the British. Early life Yardley was born in 1889 in Worthington, Indiana. He learned to use ...

American Black Chamber
The Black Chamber (1919–1929), also known as the Cipher Bureau, was the United States' first peacetime cryptanalytic organization, and a forerunner of the National Security Agency. The only prior codes and cypher organizations maintained by the US government had been some intermittent, and always abandoned, attempts by Armed Forces branches prior to World War I. History Headed by Herbert O. Yardley (1889–1958), the Black Chamber was founded in May 1919 following World War I. Yardley had commanded the U.S. Army cryptographic section of Military Intelligence (MI-8) during World War I. MI-8 was disbanded after the war. Jointly funded by the Army and the State Department, the Cipher Bureau was disguised as a New York City commercial code company; it actually produced and sold such codes for business use. Its true mission, however, was to break the communications (chiefly diplomatic) of other nations. During the Washington Naval Conference, it aided American negotiators by pro ...
