Wolfgang Kaiser (KgU)

It was not till 3 June 1954, during preparations for the first anniversary of the 1953 uprisings, that a Stasi spokesman mentioned Wolfgang Kaiser's execution. He did not say exactly when it had taken place.

The Party journalist-politician Albert Norden described West Berlin as a "vipers' nest", that provided the gangsters, who "want to make the lives of the Germans hellish" ("die das Leben der Deutschen zur Hölle machen sollen"). The ruling SED (party) developed a scapegoat theory which traced the country's economic difficulties, its failings, and even the uprising of 17 June 1953 back to the show trials of 1952.

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.

The Stasi employed a third undercover informer, named Baumbach, on Wolfgang Kaiser's case. Baumbach was a friend from college days, whom they had originally mandated to use political arguments in order 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“).

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 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.

According to the defence lawyer Büsing, on the second day of the trial, during a break in the proceedings that came just before the pleadings of Prosecutor Melsheimer, the presiding judge, Hilde Benjamin explained that Kaiser would have to be sentenced to death "on the instruction of [...her] friends" ("auf Anweisung [...ihrer] Freunde"). The friends in question were the Soviet advisers observing the trial. In support of the sentence the judge went through all the KgU plans and projects, which the prosecutor had set out before the court in such abundance. That none of the dastardly plans ("hinterhältigen Pläne") had actually been carried out was, in the court's judgement, reason to be grateful for the vigilance of the security services. That day, 9 August 1952, the Supreme Court handed down the death sentence to Wolfgang Kaiser, the "incorrigible enemy of the hard working people" ("unverbesserlichen Feind des werktätigen Volkes"). Müller received a life sentence while his wife was given ten years and Hoppe twelve years in prison.

There is no sign of any formal appeals process being invoked, but on 15 August 1952 Wolfgang Kaiser's father, who lived in West Berlin, wrote a letter to Wilhelm Pieck, the East German president, begging for clemency. He enclosed two doctors' confirmations of the nervous disorders for which his son was being treated. Judge Benjamin's reply to the president on 18 August indicated scepticism regarding the sanity argument. On 1 September the Chief Prosecutor, Merlsheimer, received a letter of appeal on behalf of the Evangelical Church, written by Heinrich Grüber. Grüber hoped the death sentence could be replaced by a life imprisonment, but if the execution must go ahead he begged that Kaiser might be afforded spiritual support. Meanwhile, Merlsheimer's office wrote to Kaiser's father on 5 September calling him to a meeting.

However, on 5 September 1952 Kaiser died, without spiritual support, on the guillotine (″Fallschwertmaschine″) at the country's Central Execution location on the Münchener Platz in Dresden. He died before Merlsheimer's invitation to a meeting had reached his father (who begged to be excused from attending on health grounds: no more is known).

Very shortly before the Kaiser trial the Supreme Court of East Germany had for the first time invoked Article 6 of the Constitution, in a related case, to impose its first death sentence on Johann Burianek, another KgU member. The background to the series of show trials held in East Berlin during 1952 was the "orderly construction of socialism" ("planmäßigen Aufbaus des Sozialismus") announced by General Secretary of the Central Party Committee Walter Ulbricht in July 1952 at the second conference of the Socialist Unity Party. All this was happening in a climate of "enhanced revolutionary vigilance" ("Erhöhung der revolutionären Wachsamkeit") and "intensification of class struggle" ("Verschärfung des Klassenkampfes"). Simultaneously the German Democratic Republic was being cut off with measures that included progressively closing the external borders of West Berlin (left by the post-war settlement as a western enclave surrounded by East German territory) and the splitting of the Berlin telephone network at the end of May in response to growing threats from outside the country.

By 1952 the division of what had remained of Germany into two countries had become fact: West Germany comprising the zones formerly occupied by the United States (southern Germany), Britain (northern Germany) and France on one side and East Germany, comprising what had previously been known as the Soviet occupation zone of Germany on the other. From the East German perspective, the Kampfgruppe gegen Unmenschlichkeit (KgU / "Struggle Against Inhumanity" group) looked like a terrorist organisation led by the American spy agencies and the defendants, its members, had planned acts of sabotage, murder and terrorism. The "brutality and sadism" of Kaiser and the others convicted "knew no bounds. ..... Even the lives and health of women and children were threatened by them". (" ihre Brutalität und ihr Sadismus kennen keine Grenzen ... selbst Leben und Gesundheit von Frauen und Kindern sind von ihnen bedroht“".) In later discussions on the KgU, the "Poison alchemist Kaiser" and the "Rail bomber Burianek" were named in the same breath. Even though no evidence for the demolition of anything by the KgU existed, and no name for any East German official supposedly targeted for murder was ever produced, the trial and its aftermath made an impression with public opinion in the west. By the end of the 1952, those people who had followed the show trials were very far from convinced that the communist accusations were completely groundless. Some of the revelations about the KgU presented in West Germany's news magazine Der Spiegel during the 1950s involved matters that were already in the public sphere thanks to East German propaganda.

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'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.

Wolfgang Kaiser (born Leipzig 16 February 1924: executed Dresden 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.
