Arvid Harnack

Arvid Harnack (; 24 May 1901 – 22 December 1942) was a German jurist, Marxist economist, Communist, and German resistance fighter in Nazi Germany. Harnack came from an intellectual family and was originally a humanist. He was strongly influenced by Johann Wolfgang von Goethe but progressively moved to a Marxist-Socialist outlook after a visit to the Soviet Union and the Nazis' appearance. After starting an undercover discussion group based at the Berlin Abendgymnasium, he met Harro Schulze-Boysen, who ran a similar faction. Like numerous groups in other parts of the world, the undercover political factions led by Harnack and Schulze-Boysen later developed into an espionage network that supplied military and economic intelligence to the Soviet Union. The group was later called the Red Orchestra (Rote Kapelle) by the Abwehr. He and his American-born wife, Mildred Fish, were executed by the Nazi regime in 1942 and 1943, respectively.

Life Die vormarxistische Arbeiterbewegung in den Vereinigten Staaten: eine Darstellung ihrer Geschichte. (The pre-Marxist labour movement in the United States: an account of its history) University of Jena: G. Fischer, 1931 Harnack's family were prominent and academically gifted Protestant Germans from the Baltic region. His father was literary history professor Otto Harnack and his mother was Clara Harnack (née Reichau), an artist. Reichau was the granddaughter of Justus von Liebig, one of the principal founders of organic chemistry. Harnack's siblings were Falk Harnack, his elder brother; Inge Harnack; and Angela Harnack, a violin teacher. Harnack was the nephew of theologian Adolf von Harnack.

In 1919 he became a member of the Freikorps, a volunteer militia. From 1919 to 1923 he studied law at the Friedrich Schiller University, the University of Graz, and the University of Hamburg; he became a Doctor of Law in 1924. He completed postgraduate studies in economics in Hamburg and the London School of Economics before being awarded a Rockefeller scholarship to study at the University of Wisconsin. In Madison, Wisconsin, Harnack was influenced by the industrial economist and labor historian John R. Commons, and saw him as a mentor.

In 1926, Harnack met American literary historian Mildred Fish, also a graduate student at the University of Wisconsin, after Harnack wandered into the wrong lecture hall. After a brief friendship and romance, they were engaged on 6 June 1926 and married on 7 August 1926. The couple met Margaretha "Greta" Lorke, a German student of sociology, at a Friday evening gathering organized by Commons in Madison. A friendship that lasted for many years developed between Mildred and Lorke, the latter being drawn into an intimate group of Wisconsin radicals known as the Friday Niters Club. According to a fellow student and member of the group, Hazel Briggs Rice, the Friday Niters Club members considered themselves to be liberal Progressives. Lorke later married Adam Kuckhoff. Harnack became secretary of the group and Lenz became the president.

By 1935, Harnack was employed as a lecturer on foreign policy at the University of Berlin. On 8 August 1935, three months after Harnack joined the trade ministry, he met with Hirschfeld in a meeting that lasted three hours. During the meeting, Hirschfeld informed Harnack that his position in the trade ministry could provide useful information that could be used to defeat the Nazis, and offered to establish a system to convey the documents to Moscow. Harnack agreed to be an informer and was given the codename Balt, assigned a control officer, Alexander Belkin, and given a mission to increase his sources by building a network of contacts.

However, Hirschfeld requested that Harnack break off all relations with the KPD, and to avoid working for the resistance, but Harnack refused; he was never interested in becoming a Soviet agent, considered himself a communist, and would supply information to anybody who would take part in anti-fascist operations that helped to destroy the Nazis.

According to KGB sources, between 1935 and 1938 Harnack supplied information about German currency, German investments abroad, and details of the German foreign debt. He also provided details of secret trade agreements to Soviet intelligence. During that period, Harnack circulated the same information to other groups. In 1935, Harnack met Harro Schulze-Boysen for the first time, but Harnack decided not to meet again due to their different temperaments.

At the end of 1937, and formally on 3 March 1938, U.S. ambassador William Dodd was replaced by Hugh Wilson. Joining him as First Secretary and monetary attaché at the U.S. Embassy was Donald Heath.

U.S. Secretary of the Treasury Henry Morgenthau Jr. felt that the Berlin embassy needed a treasury attaché who could ferret out German economic information, so Heath became an intelligence agent in the office of coordination at the embassy (a forerunner of the Office of Strategic Services). His job was to recruit sympathetic informers that could provide that type of information. Mildred met Louise Heath, Donald's wife, at the American Women's Club in Bellevuestrasse in 1937. The Harnacks became friends with the Heaths, but Arvid was resistant to Donald's proposal at first; by 1938 he started providing him with intelligence.

At the start of World War II, Louise and Donald Heath Jr. fled to Norway before returning several months later. When they returned, Louise asked Mildred to tutor her son in American literature. The two couples began to regularly spend weekends together and occasionally went on vacation together. At other times Arvid and Donald met in the countryside to exchange intelligence, but it became increasingly dangerous. Between December 1939 and March 1941, Donald Jr. couriered between Harnack and the American embassy, delivered food from Denmark and Italy, and gave medicine to the Harnacks. After the war, Donald acknowledged that Arvid was his source for German economic intelligence.

In 1937, former Prussian minister of culture and religious socialist Adolf Grimme was brought into the group through Kuckhoff and playwright Günther Weisenborn. Harnack had previously met Grimme at the funeral of Adolf von Harnack on 10 June 1930. Grimme was a religious socialist who belonged to the Covenant of Religious Socialists of Germany, so Harnack used considerable effort to convince him to become a communist.

On 26 January 1937, a new civil service law gave Nazi officials the power to fire tenured civil servants. Walther Funk, Harnack's manager at the Ministry, persuaded him to join the Nazi Party to protect himself, and become what was known as a Hamburger (i.e. Nazi brown outside, Moscow red inside). In May 1937, Harnack joined the Nazi Party with the number 4153569.

Harnack's nephew, Wolfgang Havemann, became a frequent visitor to the group discussions after 1938.

Harnack/Schulze-Boysen Group

In 1940, Harnack came into contact with other resistance groups and began to cooperate with them. The most important of these was a small group called Gegner Kreis that was run by Harro Schulze-Boysen, a Luftwaffe lieutenant and descendant of an old German military family, who had known Harnack since 1935, but was reintroduced to him sometime in late 1939 or early 1940 through Greta Kuckhoff. The Kuckhoffs had known the Schulz-Boysens since 1938, and started to engage them socially in autumn 1940 by bringing Mildred and Libertas (Harro's wife) together while on holiday in Saxony. Harnack and Schulze-Boysen were wary of meeting due but finally met in October 1940 at the house of Adam's and Greta Kuckhoff apartment at Wilhelmshöher Allee 19 in Friedenau.

On 17 September 1940, the Harnacks met the third secretary member of the Soviet embassy, Alexander Korotkov who used the alias Alexander Erdberg while meeting the couple in their Tiergarten apartment. Korotkov was a Soviet intelligence agent who had been operating clandestinely in Europe for much of the 1930s as an employee of the foreign intelligence service of the Soviet People's Commissariat for State Security (NKGB), but had been dismissed during Stalin's purges. He managed to get back into the service . Initially wary and suspicious of the uninvited guest, Korotkov proposed a second meeting at the Soviet Embassy in Berlin to Harnack, where Korotkov could demonstrate his good faith and prove to Harnack that he was not a decoy. Several reasons were given as to why Harnack decided to become a spy, including a need for money, being ideologically driven, and possibly blackmail by Russian intelligence. It was known that Harnack had his own agenda, and that he wanted Germany to be separate from Nazism and the Soviet Union. According to a statement by Korotkov discovered after the war, he thought Harnack was not motivated by money or ideologically driven, but that he was specifically building an anti-fascist organisation for Germany, as opposed to an espionage network for Russian or American intelligence; Harnack considered himself a German patriot.

Korotkov considered Harnack a moral person, and that while he reported to his Soviet directors, he felt the Soviet Union "was a country whose ideals he felt connected to". Harnack often told his friends of his aversion to the Soviet Union and once told Grimme that Germany would "need a fist not to become a puppet of the Soviet Union".

On 26 September 1940, Harnack provided Erdberg with his first intelligence report that reported the Nazi state was in the planning stages for a war against the Soviet Union. In mid-April 1941, in an attempt to increase the influx of intelligence, the Soviets ordered Korotkov to create a Berlin espionage operation and Harnack was asked by Korotkov to run it. Korotkov was instructed by Soviet intelligence to provide a person in Berlin that could be contacted via radio in the event of war. Harnack refused to be contacted in that manner and agreed only to collect and encipher the material in his own apartment, but the transmission would take place somewhere else. In June 1941, with Harnack's approval, Korotkov delivered a wireless transmitter to Greta Kuckhoff during a meeting at an underground railway station. The device was mounted in a case and had a range of 600 miles, but the battery only lasted two hours. The aim of the operation was to organise the Harnack group into an independent network with direct contact with Soviet intelligence. In May, two additional shortwave radio transmitters were delivered by diplomatic pouch; one was battery powered. The second one was dismantled so that it could fit into a suitcase, and required an electrical supply to operate. However, when Adam Kuckhoff tested the first transmitter, it failed to work so it was returned the following week. Along with the radio transmitter, Korotkov gave Harnack 12,000 Reichsmarks and Adam Kuckhoff 500 Reichsmarks. Harnack distributed the money to his agents: Behrens received 5000 marks, Leo Skrzipczynski received 3,000, Grimme received 2,000, and Rose Schloesinger received 1,000. The rest of the money was used by Harnack for daily expenses

Harnack acted as the intermediary when transmitting reports, which were delivered from several people, including Schulze-Boysen, and were encyphered and passed to Hans Coppi for transmission. The courier was initially Behrens, but Schlösinger took over when Behrens became unavailable. On 1 July 1941, Korotkov and the Soviet embassy staff, along with many other Soviet citizens, left Germany.

In June 1941, after the German invasion of the Soviet Union, the resistance group intensified its leaflet propaganda. At the same time, the group started to collect military intelligence in a careful, systematic manner that could be used to overthrow the Nazis. Members of both groups were convinced that Germany could only be liberated by the Nazis' military defeat, and that by shortening the war, millions of people could be saved.

In 1941, Harnack sent the Soviets information about the forthcoming invasion. That same year, he wrote for the resistance magazine, Die Innere Front ("The Home Front"), the twice-monthly newspaper written in six languages that was created by John Sieg. In 1942, Harnack produced a study called "Das nationalsoialistische Stadium des Monopolkapitalismus" (The National stage of monopoly capitalism), published in Die Innere Front, which described the Gestapo as a tendentious and antigovernment economic treatise, and was read as far as Munich and Hamburg.

In the summer of 1942, Sieg recruited Wilhelm Guddorf, a communist writer and former editor of the Die Rote Fahne. From January to August 1942, Harnack was forced to pass his intelligence via courier. Harnack arranged with the Communist Party in Hamburg via Bernhard Bästlein to pass the reports through contacts in Flensburg and Denmark to the Soviet embassy in Stockholm. Bästlein was a close associate of Guddorf.

Discovery The discovery of the illegal radio transmissions of Soviet agent Johann Wenzel by the German radio counterintelligence organization Funkabwehr and his capture by the Gestapo on 29–30 June 1942 eventually revealed the members of the group and led to the Harnacks' arrest. Wenzel decided to cooperate after he was tortured. His exposure of the radio codes enabled Referat 12, the cipher bureaux of the Funkabwehr, to decipher Red Orchestra message traffic. The unit had been tracking Red Orchestra radio transmissions since June 1941, and found Wenzel's house in Brussels contained a large number of coded messages. Wilhelm Vauck, principal cryptographer of the Funkabwehr, received the ciphers from Wenzel. On 15 July 1942, Vauck managed to decrypt a message dated 10 October 1941 that gave the locations of the Kuckhoffs and Schulze-Boysens' apartments.

When Vauck decrypted this message, it was forwarded to Reich Security Main Office IV 2A, where they identified the people living at the three addresses. The three couples were put under surveillance on 16 July 1942. There was a member of Schulze-Boysen's group working in Referat 12 in Vauck's team: Horst Heilmann, who was supplying Schulze-Boysen with intelligence. Heilmann tried to contact Schulze-Boysen but was unsuccessful and left a message with him to phone him back. Schulze-Boysen returned the call, but Vauck answered the phone, and when he requested the name of the caller to take a message and was met with Schulze-Boysen, the deception was revealed and the group exposed.

Trial and death

On 7 September 1942, the Harnacks were arrested by the Gestapo while on a short holiday to Preila on the Curonian Spit.

Arvid was sentenced to death on 19 December after a four-day trial before the Reichskriegsgericht ("Reich Military tribunal"), and was put to death three days later at Plötzensee Prison in Berlin. He and his co-conspirators were hanged from meat hooks by piano wire, a method designed to prolong their suffering. Mildred was originally sentenced to six years in prison, but Hitler swiftly cancelled the sentence and ordered a new trial, which resulted in a death sentence. She was beheaded by guillotine, and her body was released to Hermann Stieve, anatomy professor at Humboldt University, to be dissected for research. A cenotaph was installed for the Harnacks after the war by Arvid's older brother Falk, a member of the White Rose resistance group, at Zehlendorf Cemetery.

Awards and honours On 6 October 1969, Harnack was posthumously awarded the Order of the Red Banner. This honour has been proven to be erroneous, as it mistakenly interpreted Red Orchestra as a communist spy network working for the Soviets. This interpretation of the resistance group, based on original slander by the Gestapo, was used in a similar way in the West, in which the rebels were not honoured there, but persecuted as traitors until the 1970s. In Magdeburg, a street called Harnackstraße is named after the Harnacks, as well as similar named streets in Lichtenberg, Berlin; and Reudnitz, Leipzig. In Jena, a street known as the Arvid-Harnack-Straße is named after him. In the courtyard location at Unter den Linden 6 of the Humboldt University of Berlin is a memorial stone. In Neukölln, Berlin, in the Hasenheide, on the corner of Lilienthalstraße, a plaque commemorates the Harnacks and Heym. Stolpersteins for the Harnakcs were laid in front of 14 Genthiner Straße 14 in the Tiergarten on 20 September 2013 in the presence of US Ambassador John B. Emerson.
