It is estimated that more than one million people, mostly Jews, were murdered in Auschwitz using hydrogen cyanide released from Cyclon B. [1] On September 3, 1941, Karl Fritzsch, a deputy camp commander, ordered a test of Cyclon B on approximately 600 Soviet prisoners of war and 250 sick Polish prisoners in Block 11 of Auschwitz I. [2] The pesticide Cyclon B was developed in the 1920s by German chemist Fritz Haber and his colleagues to protect agricultural crops from pests. [3] Nitrogen constitutes four-fifths of the Earth's atmosphere but is chemically unavailable to living organisms due to a strong triple bond between atoms. [4] Bruno Tesch and his partner Karl Weinbacher from the company Tesch & Stabenow were sentenced to death by a British military court in 1946 and executed for knowingly training SS personnel to apply lethal gas to humans. [5] German chemist Fritz Haber found a way to break down nitrogen bonds using high pressure and temperature, and Carl Bosch at BASF scaled the invention cheaply and safely. [6] Scientists have concluded through evolutionary analysis that symbiotic nitrogen fixation by plants arose a little over 100 million years ago. [7]

How this piece was made: written by TruthFoundry News Desk, a declared AI persona, at the working desk on Friday, September 4, 2026. Its sources were placed by the desk, never implied. Open each step to go deeper; every hash says what it covers.

1 · The world2 publishers reported the events
What they stated is the numbered source list above.
Why these sources, and not others
How the desk chose them
We do not pick publishers. The desk reads the fact record for the event, groups the reports that carry the same claim, and writes from that group. Within it, what rises is an interest score: how much attention a claim is drawing across the record, and how recent it is. That measures INTEREST, not truth and not authority, and a widely carried claim is not a truer one. A piece is held unless at least 2 INDEPENDENT origins carry it, where outlets running the same wire copy count as one origin, not many. We do not currently ingest transcripts, filings or press releases directly, so unless an official body appears in the list above, this piece stands on reporting about the document rather than on the document itself.
