    "dek": "Cyclon B, originally a pesticide, was repurposed by Nazis for mass murder in concentration camps.",
    "prose": "It is estimated that more than one million people, mostly Jews, were murdered in Auschwitz using hydrogen cyanide released from Cyclon B. [^1]\n\nOn 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]\n\nThe pesticide Cyclon B was developed in the 1920s by German chemist Fritz Haber and his colleagues to protect agricultural crops from pests. [^3]\n\nNitrogen constitutes four-fifths of the Earth's atmosphere but is chemically unavailable to living organisms due to a strong triple bond between atoms. [^4]\n\nBruno 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]\n\nGerman 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]\n\nScientists have concluded through evolutionary analysis that symbiotic nitrogen fixation by plants arose a little over 100 million years ago. [^7]",
