A gas chamber is an apparatus for killing humans or other animals with gas, consisting of a sealed chamber into which a poisonous or asphyxiant gas is introduced. Poisonous agents used include hydrogen cyanide and carbon monoxide.
General Rochambeau developed a rudimentary method in 1803, during the Haitian Revolution, filling ships' cargo holds with sulfur dioxide to suffocate prisoners of war. The scale of these operations was brought to larger public attention in the book Napoleon's Crimes (2005), although the allegations of scale and sources were heavily questioned.
In America, the utilization of a gas chamber was first proposed by Allan McLane Hamilton to the state of Nevada. Since then, gas chambers have been used as a method of execution of condemned prisoners in the United States and continue to be a legal execution method in three states, seeing a possible, legislated reintroduction, although redundant in practice since the early 1990s.
Lithuania used gas chambers for civilian, penal use in the 1930s, with the last known execution carried out in 1940. The Soviet Union allegedly used the method to perform executions during the bloody Great Purge, including by use of gas vans. Prisoners were gassed on the way to the Butovo firing range, where the NKVD normally executed its prisoners by shooting them. None of these saw mass use, however, and were strictly for "criminal" purposes.
Most notably, during the Holocaust large-scale gas chambers designed for mass killing were used by Nazi Germany from the late 1930s, as part of the Aktion T4, and later for its genocide program.
More recently, escapees from North Korea have alleged executions to have been performed by gas chamber in prison camps, often combined with medical experimentation.

The Holocaust was the genocide of European Jews during World War II. Between 1941 and 1945, Nazi Germany and its collaborators systematically murdered some six million Jews across German-occupied Europe, around two-thirds of Europe's Jewish population. The murders were carried out primarily through mass shootings and poison gas in extermination camps, chiefly Auschwitz-Birkenau, Treblinka, Belzec, Sobibor, and Chełmno in occupied Poland. The Nazis developed their ideology based on racism and pursuit of "living space" and seized power in early 1933.
Adolf Hitler (ˈaːdɔlf ˈhɪtlɐ; 20 April 1889 - 30 April 1945) was an Austrian-born German politician who was the dictator of Germany from 1933 until his suicide in 1945. He rose to power as the leader of the Nazi Party, becoming the chancellor in 1933 and then taking the title of Führer und Reichskanzler in 1934. During his dictatorship, he initiated World War II in Europe by invading Poland on 1 September 1939. He was closely involved in military operations throughout the war and was central to the perpetration of the Holocaust, the genocide of about six million Jews and millions of other victims.
From 1933 to 1945, Nazi Germany operated more than a thousand concentration camps (Konzentrationslager), including subcamps on its own territory and in parts of German-occupied Europe. The first camps were established in March 1933 immediately after Adolf Hitler became Chancellor of Germany. Following the 1934 purge of the SA, the concentration camps were run exclusively by the SS via the Concentration Camps Inspectorate and later the SS Main Economic and Administrative Office.
This paper describes the first development and implementation of a closed loop edge localized mode (ELM) frequency controller using gas injection as the actuator. The controller has been extensively used in recent experiments on JET and it has proved to wo ...
