Wolfgang Kaiser (16 February 1924 – 6 September 1952) was a member of Rainer Hildebrandt's "Struggle against Inhumanty" group (KgU / Kampfgruppe gegen Unmenschlichkeit) which campaigned against the one party dictatorship in the German Democratic Republic.
In the 1952 Hildebrandt conspiracy show trial, he was identified on 8 August as the "chief chemist" of the KgU and, on 9 August, condemned to death in the country's Supreme Court.
Life
Background Wolfgang Kaiser was a chemistry student. He was studying at the Humboldt University, then in East Berlin, though he actually lived in West Berlin. The political division of Berlin complicated his life. He attempted without success to switch to the newly established Free University in West Berlin, but lost his student place in the process.Gerhard Finn: Nichtstun ist Mord. Die Kampfgruppe gegen Unmenschlichkeit - KgU, Westkreuz-Verlag, Bad Münstereifel 2000,
The "Struggle against inhumanity group" "Die KgU" / "Die Kampfgruppe gegen Unmenschlichkeit") Now unemployed, Kaiser offered his services as a chemicals expert to the recently established KgU, with which he was politically in sympathy. From early 1951 the KgU placed a former multi-occupancy rabbit hutch at his disposal, in the garden of their premises in Berlin's Nikolassee district. Later his work as the KgU's chemistry expert transferred to three basement rooms in an apartment which the movement rented at Kurfürstendamm No.106, in the city's central Halensee district. Kaiser continued through this time to receive unemployment benefit: he was not an employee of the KgU. He did, however, receive a small honorarium from them, initially of 50 Marks per month, and which in May 1951 was doubled to 100 Marks.
Kaiser made fuses for "leafleting balloons", which the KgU used in order to rain down, in large quantities, leaflets, newspapers and other reading material onto the German Democratic Republic.Kai-Uwe Merz: Kalter Krieg als antikommunistischer Widerstand. Die Kampfgruppe gegen Unmenschlichkeit 1948-1959 (=Studien zur Zeitgeschichte, Band 34), Oldenbourg, München 1987 He also produced smoke grenades, stink bombs and incendiary materials which could be used to torch targets such as propaganda noticeboards. The incendiary material was kept in small ampoules, each with a capacity of approximately two cubic centimeters, which the "Resistance Department" of the KgU could distribute to activists. In his rooms Kaiser kept a large number of these ampoules which he seems to have used in experiments involving small quantities of all sorts of chemicals that he got hold of, including the nerve agent Cantharidin.
The "Ministry for State Security" ("Das MfS" / "Das Ministerium für Staatssicherheit" or, colloquially, "The Stasi") Kaiser's activities and his identity were known to the East German Ministry for State Security (the Stasi) through an undercover Stasi informer called Gustav Buciek. The KgU had been using Buciek as a messenger since 1951. Even after he took a job with the Telegraf newspaper, Buciek's criminal past, which was unknown to his employer, still enabled the Stasi to blackmail him. According to Buciek's reports, Kaiser's improvised laboratory contained neither laboratory equipment nor chemistry related materials.
Kaiser purchased the chemicals for his experiments and other activities from a shop called Drogerie Gläser. The shop owner was another undercover Stasi informer. From time to time Kaiser, when buying his supplies, would let drop a remark about some forthcoming "big event", and the conversation would be reported to the Stasi by "Secret agent Gläser". Matching the reports from Busiak with Gläser's information about the nature and quantities of his supplies, the Stasi were able to infer that Kaiser was purchasing items such as invisible ink, explosives, metal dissolving acids and other items suitable for planning and carrying out acts of sabotage.
The Stasi employed a third undercover informer, named Baumbach, on Wolfgang Kaiser's case. Baumbach was a friend from college, whom they had originally mandated to use political arguments to dissuade Kaiser from his KgU activities. In the end Baumbach identified himself to Kaiser as a "senior Stasi operative" and was paying Kaiser, whose alcohol fueled life-style left him permanently short of money, small amounts of 20 or 30 Marks in return for information about the KgU. The Stasi found out from "Secret agent Gläser" that Baumbach had blown his own cover to Kaiser, and they also knew that he was supplying incomplete reports on Kaiser to his Stasi contact. After Kaiser had disclosed to Baumbach plans for a KgU mass leaflet drop scheduled for 1 May 1952, Baumbach offered him the opportunity to resume his studies at the Humboldt University provided he would at the same time collaborate with the Stasi (bei gleichzeitiger „Zusammenarbeit mit dem MfS“).
Arrest On 8 May 1952, at three o'clock in the morning, Wolfgang Kaiser, probably acting under the influence of alcohol, armed himself with a pistol, a baton, and a drugged cigarette. Accompanied by "Agent Baumbach" who was similarly armed, he then presented himself at an East Berlin Police station and accepted the offer that Baumbach had supposedly delivered from the Stasi. The two of them were arrested.
The charges Charges (which disclosed the extent of the surveillance under which he had been operating) laid against Kaiser the next day, were to the effect that he had endangered world peace and carried out acts of sabotage and diversionary actions, while acting as an agent of the "Ildebrandt'schen" [i.e. relating to Rainer Hildebrandt] "Terror and Espionage organisation" [ie the KgU]. He had produced explosives, phosphorus ampoules, incendiary stuff etc. in order to carry out acts of sabotage.„...den Frieden der Welt gefährdet und Sabotage und Diversionshandlungen durchgeführt zu haben, indem er als Agent der Ildebrandt'schen [sic!] Terror- und Spionageorganisation Spionageaufträge durchführte und aktiv durch die Herstellung von Sprengstoff, Phosphorampullen, Brandsätze [sic!] usw. für die Durchführung von Sabotageakten tätig war.“ Following their arrest Kaiser and Baumbach were handed over to the Stasi.
After the Stasi investigators had established that Kaiser was not known to any of the prisoners with KgU contacts in East German jails, they sent Kaiser for trial in the Supreme Court, where he was to be confronted by evidence from three other KgU members from East Germany, these being the Müller couple from Zerpenschleuse and Kurt Hoppe, a finance worker from Potsdam.
Evidence gathering Joachim Müller had undertaken an unsuccessful arson attack against a temporary wooden Autobahn bridge at Finowfurt, he had successfully employed a stink-capsule to make a polling station unusable. he had scattered "tyre destroyers" on the road, and he was intending to blow up the old lock along the recently opened Havel Canal at Paretz. His wife, Ursula, had been a "courier", providing a link to the KgU. Under interrogation the Müllers confessed to a lengthy list of planned and/or enacted sabotage schemes, of which hardly any had been crowned with success. Ursula Müller stated that a KgU member, "most likely" Ernst Tillich, at that time the campaigning group's leader, would have wished to drive a car to Finowfurt with a petrol/gasoline canister, incendiary equipment and "tyre destroyers" in support of a plan to burn down the nearby "Kaiser Bridge". Sabotage tools, including incendiary devices, for Müller and other unknown saboteurs had, on his own admission, been produced by Kaiser.
Hoppe had facilitated "administrative damage" to the East German economy by helping the KgU with the distribution of financially sensitive "news items", original forms and printed circulars. The Müllers and Hoppe were not known to each other.
Trial
Pretrial The defendants were imprisoned in an underground cell (known as a "submarine") at the main Stasi prison, Hohenschönhausen, and here the Stasi prepared them for the trial process.Besondere Richtlinien für die Vorbereitung von Schauprozessen hatten im Januar 1952 Generalstaatsanwalt und Justizminister der DDR in einer „Gemeinsamen Rundverfügung“ an die Staatsanwaltschaften und Gerichte bekanntgegeben, teilw. im Wortlaut bei Karl Wilhelm Fricke: Politik und Justiz in der DDR. Zur Geschichte der politischen Verfolgung 1945–1968. Bericht und Dokumentation. Verlag Wissenschaft und Politik, Köln 1979, , S. 273f. It was here that Chief State Prosecutor Melsheimer, witnessed by a Soviet officer, threatened Müller that he would ask the court to apply the death sentence if Müller failed to testify in line with the indictment.... er werde „auf Todesstrafe plädieren“, wenn dieser (Müller) nicht aussage, „was in der Anklage steht“. At the same time the Supreme Court vice-president Hilde Benjamin, who would herself be presiding at the trial, gave notice in a pretrial meeting with the defense lawyers, whose participation in the actual trial proceedings would be minimal, that they should not expect any death sentences.Testimony of defense lawyer Büsing who later escaped from East Berlin to West Berlin and there repeatedly gave statements about the KgU.

Public justice The trial of Wolfgang Kaiser began in the Supreme Court, presided over by the Court's Vice-president, Hilde Benjamin, on 8 August 1952. Publicity was maximised with numerous journalists present from both west and east. Extracts of the proceedings were even broadcast on the radio. The lawyer who was there to defend Kaiser, a Dr.Büsing (who later defected to the west), had the impression that the Stasi had "prepared" ("behandelt") the defendants. During their "preparation" they had been "incriminated over things that had not been known to the defense, and which could not be found in the papers filed with the court" ("„mit Dingen belastet, die weder der Verteidigung bekannt waren, noch dem Akteninhalt entnommen werden konnten"). Ernst Melsheimer, who was prosecuting, presented Kaiser as the "Chief of the KgU's chemical-technical lanboratory" (der "Leiter des chemisch-technischen Labors der KgU"). He referred to Johann Burianek who had been executed at the beginning of August, following conviction in another show trial based on alleged KgU sabotage plans. He produced an expert witness who testified that the potassium chlorate and ammonium nitrate in the possession of Kaiser and the "explosives case" passed to Burianek were not suitable to blow up the railways bridge, but might at the most dissolve the rails. Melsheimer invited the court to conclude, therefore, that the possible torching of the bridge was no more than a "bravura scenario", and his expert witness did not refute Melsheimer's inference.Gerhard Finn: Nichtstun ist Mord. Die Kampfgruppe gegen Unmenschlichkeit - KgU, Westkreuz-Verlag, Bad Münstereifel 2000, , Finn bases himself on Stasi archives (page 131) and also cites Merlsheimer's exchanges with the court officers (page 132).
Nerve agent
Merlsheimer showed particular interest in 25 gm of the nerve agent cantharidin that Kaiser had acquired. Although the Resistance Department of the KgU had issued doses of the poison to some of their contacts in East Germany, there was no evidence that any had been used,Karl Wilhelm Fricke, Roger Engelmann: „Konzentrierte Schläge“: Staatssicherheitsaktionen und politische Prozesse, Schriftenreihe des BStU, 11, Page 87 which meant that this line of attack could be presented to the court only in terms of what might theoretically be possible. Melsheimer explained, however, that under a best case scenario, administering doses intravenously ("bestmöglicher intravenöser Anwendung"), 25,000 people could be killed with Kaiser's cantharidin.
