Tesch & Stabenow


This now closed company few has heard about, but say Zyklon B it will be different. Tesch & Stabenow was one of two companies that sold Zyklon B to the SS who in turn used it to murder people in gas chambers. The history of Zyklon B dates back to March 1919 when several chemical companies in Germany founded DEGESCH (Deutsche Gesellschaft for the German pest control company). One of the companies was called Degussa (Deutsche Gold- und Silber-Scheideanstalt), which since 1916 was the leader in the German market for the production of pesticides against vermin. in 1920, DEGESCH produced a stable and odourless vermin-control gas called Zyklon A. In 1922, another researcher at DEGESCH, Walter Heerdt, sought help from the team, patent for a poison gas called Zyklon B (chemical name HCN). The patent was approved in 1926 and Zyklon B was produced and sold as a pesticide both in and outside Germany.

Several of the companies that co-founded DEGESCH sold their shares in the early twenties to Degussa. Degussa became by far the largest shareholder in DEGESCH with its 85 percent. However, to raise additional capital for the company, Degussa sold half of its shares to IG Farben. Degussa’s main task was to secure patents. The production of Zyklon B was carried out by Dessauer Werke, another number of subcontractors (including IG Farben) supplied the components necessary for the production of Zyklon B. DEGESCH sold the finished gas to Degussa, which in turn sold the sales rights to two companies, Heerdt and Linger GmbH (Heli) and Tesch & Stabenow (Testa), to reduce expenditure. Heli and Testa then divided the market by giving Heli the sales rights west of the River Elbe while Testa got the east side. Heli delivered Zyklon B to Mauthausen while Testa delivered to Neuengamme, Ravensbruck, Sachsenhausen, Stutthof, Majdanek and Auschwitz.

Zyklon B was used by the German army (Wehrmacht) and SS to disinfect barracks. But Zyklon B will always be known for being the gas the SS used to systematically murder people, mainly Jews. Zyklon B was inserted into the gas chamber antigen via gaps in the wall or ceiling. Zyklon B was used on humans for the first time in the Nazi Euthanasia program, although carbon monoxide was the most common gas in the Euthanasia program. The first time Zyklon B was used in the concentration camps was in the early 1940s when the SS tested the gas on about 250 gypsy children in Buchenwald. In Auschwitz, Zyklon B was tested for the first time in September 1941 on about 800 prisoners in the basement of block 11.  Zyklon B is a blistering crystal which, when in contact with air, forms a toxic hydrogen cyanide gas that attacks the cytochrome of cells in the respiratory system, where 90 percent of the oxygen is recovered. Zyklon B is corrosive and also causes enormous pain in the throat, nose, stomach, mouth and mucous membranes. Zyklon B is most effective at a temperature of 25 degrees and above. The body heat from the people in the gas chamber guaranteed temperatures of at least 25 degrees.

Between 1942 and 1944, production of Zyklon B more than doubled compared to the years 1940 and 1941. But in the end, it was no more than about 5% of the total amount of Zyklon B delivered to Auschwitz that was used to murder people. When the SS ordered Zyklon B, they requested that the special smell of bitter almond be removed and made odorless. In accordance with German law, Zyklon B contained a strong odor of bitter almonds as a form of warning. But this warning, for obvious reasons, the SS wanted to withhold the people they were about to murder. Zyklon B was delivered in the form of pellets in containers of varying sizes and because the gas was odorless, the safety of the gas was more rigorous than in normal cases.

My comment:

There are still companies trying to use the term Zyklon in their marketing, but the reactions of Jewish groups do not wait and companies will have to find other names. Tesch & Stabenow Director Bruno Tesch was sentenced to death after the war for his involvement in the distribution of Zyklon B to, among others, Auschwitz.
