Question: The Carnot wall takes its name from a man who died in what year?
Context: Mega Man Xtreme 2, known as Rockman X2: Soul Eraser (ロックマンX2 ソウルイレイザー ) in Japan, is a video game developed by Capcom for the Game Boy Color handheld game console.  It is a spin-off title in the "Mega Man X" series and is a follow-up to "Mega Man Xtreme", released the previous year.  "Mega Man Xtreme 2" takes place during the 22nd century, in an unknown year 21XX, between the events of "Mega Man X3" and "Mega Man X4".  The DNA souls of robots known as "Reploids" all around the world are being stolen by a pair of villains in order to create an army of undead "Mavericks".  The "Maverick Hunters" Mega Man X and Zero quickly spring into action, now with the help of their young ally Iris. A swallow's nest organ (French: "orgue en nid d'hirondelle" , German: "Schwalbennestorgel" ) is form of pipe organ which takes its name from its resemblance to the nests built by swallows.  Rather than placed on a gallery or on the floor, the swallow's nest organ case sits on a platform suspended on a wall, with the wall as its sole support.  In some churches it was wedged into the triforium (a shallow arched gallery built into a wall above the nave).  In swallow's nest organs from the Renaissance period, the base of the suspended platform, called a "tribuna", typically tapered into a point.  There is generally only room in a swallow's nest for one person, the organist, who accesses it by a ladder or from a staircase concealed behind the wall. Henry O. Studley (1838-1925) was an organ and piano maker, carpenter, and Mason who worked for the Smith Organ Co., and later for the Poole Piano Company of Quincy, Massachusetts.  Born in 1838 in Lowell, Massachusetts, Studley is best known for creating the so-called Studley Tool Chest, a wall hanging tool chest which cunningly holds 245 tools in a space that takes up about 40 by 20 inches (102 × 51 cm) of wall space when closed.  Studley joined the Massachusetts Infantry at the start of the Civil War and was captured in Galveston, Texas in 1863.  After the war he returned to Quincy and joined the Rural Masonic Lodge.  He died in 1925 and was remembered in his obituary in the Quincy "Patriot-Ledger" for his remarkable tool chest, among his other achievements. An annual calendar is a representation of the year that expires with the year represented, or that must be altered annually to remain current.  The term takes different but related meanings across two contexts.  One is for static (synchronic) calendars, such as wall calendars or calendar systems.  The other is for dynamic (diachronic) calendars, such as digital calendars or timepieces.  Static representations of the Gregorian calendar year are annual, because the weekdays of Gregorian dates vary from year to year.  The calendar representing one year will not serve for the next year.  With perennial calendars, the same representation of the year serves for every year.  Perpetual calendars, in this context, are computation devices for determining the weekdays of dates in any given year, or for representing a wide range of annual calendars. Smoky Wall ( ) is a prominent mountain block, 1,840 m, in the northwest part of the Salvesen Range of South Georgia.  The name "Wetterwand" (weather wall) was given to this mountain by the German group of the International Polar Year Investigations, 1882–83, but the name did not become established.  The feature was surveyed by the SGS, 1951–52, who reported that when viewed from the northeast, its summit is level and regular and has the appearance of a wall.  The descriptive name Smoky Wall was recommended by the United Kingdom Antarctic Place-Names Committee (UK-APC) in 1954. Woods Runner is a 2010 young adult novel by Gary Paulsen that takes place during the year 1776.  It is about a 13-year-old boy named Samuel living during the Revolutionary War whose house is burnt down by British soldiers.  When Samuel investigates the scene of devastation, he finds dead bodies, but none of the bodies were his parents.  The parents were not killed because one of the officer wanted somebody to play with in chess.Samuel starts a journey to find his parents in New York but gets hit in the head with a tomahawk and with the help of rebels is healed.  Before Samuel finds his parents and is able to save them with the help of a man named Abner he saves a little girl named Annie and takes her with him on his journey.  Samuel's family then adopts Annie as their own daughter.  The novel ends by saying that Samuel decided to go to war but returned home after a man who had helped him earlier died. Flowers on the Wall is the debut studio album by the Statler Brothers.  It produced their debut single "Flowers on the Wall", a Top 5 country and pop hit that year.  Members of Johnny Cash's band, the Tennessee Three played on the album, as it was recorded in between takes during the recording of a Johnny Cash album. A Carnot wall is a type of loop-holed wall built in the ditch of a fort or redoubt.  It takes its name from the French mathematician, politician, and military engineer, Lazare Carnot.  Such walls were introduced into the design of fortifications from the early nineteenth century.  As conceived by Carnot they formed part of an innovative but controversial system of fortification intended to defend against artillery and infantry attack.  Carnot walls were employed, together with other elements of Carnot's system, in continental Europe in the years after the final defeat of Napoleon in 1815, especially by the Prussians, other Germans and Austrians.  Their adoption was initially resisted by the French themselves and by the British. Lazare Nicolas Marguerite, Count Carnot (13 May 1753 – 2 August 1823) was a French politician, engineer, freemason and mathematician.  He was known as the "Organizer of Victory" in the French Revolutionary Wars. Littlehampton Redoubt, usually known as Littlehampton Fort, was built in 1854 to protect the entrance to the River Arun at Littlehampton on the south coast of England, against possible attack by the French under the Emperor Napoleon III.  There had been a previous battery on the east bank of the river, but the new fort was built on the west bank.  It consisted of a platform from which cannon could sweep the harbour mouth, with a barracks behind and a surrounding defensive ditch and wall.  The fort was an innovative military structure, incorporating the new feature of a Carnot wall.  Its active use as a fort was short at only about 20 years, owing to technical changes in armaments, but it was a precursor of the later Palmerston Forts.  Having had various uses since decommissioning, it is now in a ruinous and overgrown state.
