Harald Tachau, born on 21 Oct. 1904 in Hamburg, deported on 19 Nov. 1942 to Auschwitz

Oberstrasse 14 (Harvestehude)

Harald Fritz Tachau was born in 1904 in Hamburg as the fourth son of the lawyer Albert Tachau (born on 21 Dec. 1865 in Ribe/Denmark, parents: Charles Adolph Tachau, died on 10 May 1867, and Jenny Israel, died on 30 Oct. 1929) and of the Hamburg native Else Tachau, née Rosenblum (1872–1934, parents: Albert Rosenblum and Agnes Schiff).

In 1894, after his second state legal examination, his father Albert Tachau settled in the Hanseatic city as a lawyer (at Grosse Bleichen 5) and was admitted to the Hanseatic Higher Regional Court (Hanseatisches Oberlandesgericht), the Regional Court (Landgericht), and the Hamburg District Court (Amtsgericht). In Aug. 1895, he married in Hamburg. Starting in 1919, he ran a joint law office with Paul Tentler (1871–1958) and Alfred Kauffmann (1879–1949), which was moved a few years later from Hamburger Hof (at Jungfernstieg 26-33) to nearby Esplanade 1a and expanded to include the lawyers Wilhelm Kersten, Hans Scherzberg, and James G. Kauffmann (1880–1967). The publications of attorney Albert Tachau in the Hanseatische Gerichtszeitung in 1915 ("Ist ein Räumungsanspruch abtretbar" ["Is an eviction claim transferable”]) and in the Hanseatische Rechts- u. Gerichtszeitung in 1928 ("Untersuchungsrecht des Käufers beim Kauf Kassa gegen Dokumente" ["Right to examine of purchaser when buying cash against documents”]) suggest that his work focused on commercial law.

Harald Tachau had three older brothers: Walter Julius Tachau (born on 30 Apr. 1897 in Hamburg) and Hans Tachau (born on 31 Jan. 1901 in Hamburg); both studied and obtained their doctorates. His older brother Walter established himself as a lawyer in Hamburg like his father; his brother Hans became a doctor. The oldest brother, Carl Rudolph Tachau (born on 30 Apr. 1896 in Hamburg), died in 1916 as a soldier in Romania.

Harald Tachau attended the preschool of Eppendorf Oberrealschule [a secondary school without Latin] and then from Oct. 1914 to 1922, the Heinrich Hertz Gymnasium (high school) up to completing the grade 11 leaving examination (Obersekundarreife). In 1922, he began a two-year apprenticeship at the Alexander Levy banking house (founded in 1897, based at Neuer Wall 10). Due to massive personnel cuts (150 employees as a result of hyperinflation), Harald Tachau, too, was dismissed in Sept. 1925. He then temporarily attended the Berlitz School in Hamburg to improve his English language skills. From Jan. 1927 to 1930, he worked as a stock exchange representative and stockbroker for the renowned Hamburg-based L. Behrens & Söhne banking business; however, he was also dismissed from that position in the course of staff reductions – possibly in connection with the world economic crisis. He subsequently tried his hand as a traveling salesman on a commission basis in various industries, but only with moderate success.

Since 1917, Harald Tachau was a member of the Hamburg Sports Club (HSV), where he was active in track and field and hockey. He received various athletic awards. On top of his job, the slim Harald Tachau, 1.71 meter in height (about 5 ft 7 in), had passed an examination as a sports teacher for gymnastics and track and field in 1925 and then worked for six years as an honorary coach and youth leader at the HSV in the fields of track and field, handball, and soccer. He had to leave the club in 1930 due to charges of theft.

The family lived in Harvestehude, an upscale residential area of the Hanseatic city, corresponding to the economic position of the lawyer Albert Tachau. The addresses of the Tachaus there were Hochallee 41 (1896–1901), Hochallee 27 (1902–1919), and Oberstrasse 14 on the second floor (1920–1934). In 1930, according to entries in the Hamburg directory, the widow Else Tachau and the lawyer Walter Tachau resided at Oberstrasse 14; in the 1932 and 1933, only the business address of Walter Tachau’s law office was printed (Mönckebergstrasse 8, Barkhof house no. 3). Harald Tachau had already moved out in 1927 after disagreements at home.

In Oct. 1931, the Hamburg District Court sentenced Harald Tachau and Herbert Schulz (born on 1911 in Pritzwalk) to four months in prison each for joint extortion. They had sent the merchant and HSV member Karl Rave an anonymous blackmail letter and demanded 200 marks, or else they would make his homosexual inclinations public. Harald Tachau, who had no prior conviction, was granted parole for the remaining 53 days following a request for clemency in Mar. 1932.

Before the conviction, Harald Tachau’s residential address was Klaus-Groth-Strasse 56 on the fourth floor with the engineer Curt Arthur Schmidt (in Hamburg-Borgfelde). Possibly, in connection with the start of the trial, he lived from the fall of 1931 to the summer of 1933 with the general agent and supporting HSV member Paul Benthien, who believed in his innocence, at Rothenbaumchaussee 22. Benthien had learned through his sons, who were also active at HSV, that Tachau wanted to take his own life. Thereupon, he offered Tachau to hire him as an employee in his company, provided that Tachau’s rumored homosexuality would turn out to be a rumor only. However, for whatever reason, the employment relationship was short-lived.

In 1934, Harald Tachau was given a position at the Hamburg branch of the Simon Hirschland banking house, first as a messenger and later as a bank employee, but was dismissed in June 1936 when his criminal record became known. After that, the 31-year-old Harald Tachau is said to have attempted the first suicide; in Sept. 1937, he undertook a second attempt using pills, but he was found in time and stayed in hospital for three weeks. He remained unemployed and received 11 marks a week in assistance from the employment office.

The unmarried Harald Tachau was an unemployed bank employee according to the Jewish religious tax (Kultussteuer) card file of the German-Israelitic Community, to which he had belonged as an independent member since Jan. 1937. The Jewish Community noted in the card file two (partly difficult to decipher) addresses, which involved subtenant relationships: at Ludwigstrasse 2 on the fourth floor with Behre and later at Drehbahn 27 (in Hamburg-Neustadt).

Shortly after the "seizure of power” ("Machtergreifung”), the Nazi regime had enacted a series of laws: Based on a racially homogeneous "German national community” ("Volksgemeinschaft”), which morally and politically lived according to the Nazi stipulations, dissenters were excluded, persecuted, and murdered. As early as 1933, the judiciary took into account the Nazi viewpoint with complaisant judgments. On 28 June 1935, Sec. 175 of the Reich Criminal Code (Reichsstrafgesetzbuch) was tightened. Instead of "unnatural sexual offenses” ("widernatürliche Unzucht”), the law now referred only to "sexual offenses,” giving the courts greater latitude.

Due to his Jewish descent and his homosexuality, Harald Tachau inevitably came into conflict with the Nazi persecution bodies. Starting in the summer of 1937, the 24th Office of the Criminal Investigation Department Department (24. Kriminalkommissariat) in the Stadthaus expanded the systematic persecution of homosexuals. The number of convicted homosexuals had already risen massively in Hamburg: from 103 (in 1932) to 370 (in 1933) and 1,095 (in 1936) persons.

Testimony from other investigation proceedings gravely incriminated Harald Tachau due to offenses against Sec. 175. On 4 Dec. 1937, Tachau’s sublet room with Emma Behre, née Bluhm, at Ludwigstrasse 2 on the fourth floor (in Hamburg-St. Pauli), where he had lived since the end of 1936, was searched in the morning. Photographs, among other things, were seized as evidence of the crime. Afterward, he was taken to the 24th Office of the Criminal Investigation Department, where Kriminal-Oberassistent ["senior criminal investigation assistant”] Karl Conrad (born in 1899 in Friedrichstadt, in the police service since 1925, since 1931 with the criminal investigation department/vice division, since 1937 Nazi party [NSDAP] member) interrogated him. In addition to Tachau’s own crimes, Conrad also tried to learn from him criminally relevant acts of other men. After the interrogation, Harald Tachau was transferred to the Fuhlsbüttel police prison, where he was taken into "protective custody” ("Schutzhaft”). The order necessary to do so had been issued by Gestapo officer Baumann.

Ten days later, Harald Tachau was picked up for the second interrogation, with Conrad sitting opposite him again. This time, the questioning was about the places where Tachau had met men. He did name the "Porterstuben” (on Rostocker Strasse), "Zu den drei Sternen” (at Hütten 60), "Tuskulum” (at Baumeisterstrasse 17/Hansaplatz), and "Schwarzes Meer” (at Bleichenbrücke 10), as well as the "Marienburg” (on Marienstrasse), and the "Kolibri”; but he stated that he had not known the men with whom he had contact there. He emphasized that he had visited these venues between the end of 1929 and Oct. 1931. For shorter past meetings, he only vaguely referred to the area "at Millerntor.”

As it became known from parallel interviews with witnesses, Harald Tachau also frequented the "Deutschlandhaus,” the "Alsterpavillon,” the "Tanzkaffee Faun,” and the State Opera. Even during the third interrogation on 5 Jan. 1938, he did not mention the names of male sexual partners. He hoped for exoneration from a former girlfriend who was interrogated by Conrad on 13 January.

On 17 and 22 Jan. 1938, criminal investigation assistant (Kriminal-Assistent) Adolf Lenuck (born in 1906 in Bad Oldesloe, changed 1930 from the merchant marine to the police, since 1935 NSDAP member, since 1937 with the Hamburg criminal investigation department) conducted the interrogation of Harald Tachau and presented photographs from the homosexuals register of the police in order to obtain the names of other men together with incriminating statements from Tachau. In vain. After confronting Tachau with the photographic file yet again on 2 Feb. 1938, Conrad drew an interim conclusion: "Tachau now probably told the truth, even though one may have doubts as to whether he really does not know his accomplices. Huppertz has not been questioned, as his deed occurred as early as 1930.” Hubert Huppertz was the only name that Harald Tachau had given away and not by coincidence, that deed was already past the statute of limitations.

After examining the accused, Judge Joachim Lohse (a member of the NSDAP and the SA since 1933) of the Hamburg District Court issued an arrest warrant on 17 Feb. 1938 due to danger of collusion and expected new criminal offenses. At the same time, Harald Tachau was transferred from protective custody to pre-trial detention. The summary court or abridged proceedings by a court of lay assessors (Schöffengericht) pronounced the verdict on 12 Mar. 1938. Associate judge at the District Court (Amtsgerichtsrat) Joachim Lohse (1901–1997, Chairman), Karl Wahl (lay assessor) and Nikolaus Wedemeyer (lay assessor) sentenced Harald Tachau to one year in prison and to paying the costs for "sexual offenses with men” between 1933 and 1937. However, the ‘preparation of a bill of costs’ was abandoned, as Harald Tachau was completely destitute. Public prosecutor Nicolaus Siemssen (born in 1901 in Fuzhou/China, since 1933 member of the NSDAP and the SA) had demanded a penalty six months higher. However, even the level of the punishment actually imposed could only be achieved by a rather far-reaching legal interpretation: "The individual actions of the defendant still fall partly under the purview of Sec. 175 StGB [Criminal Code] old version. (...) Apart from that, since it involves a single act in the legal sense, the extent of the penalty is to be taken from Sec. 175 StGB new version.”

On 6 Apr. 1938, Harald Tachau was committed to prison; his release from Glasmoor prison near Glashütte was scheduled for 9 Dec. 1938. The notes of the prison administration on written appeals by the prisoner Tachau provide information about his wishes and concerns (and the reaction of the prison bureaucracy): In Feb. 1938, he applied for permission to order the newspaper Hamburger Anzeiger ("approved”), requested transfer to solitary confinement due to insomnia and agitation ("instructed”), in Mar. 1938, permission to visit the Rabbi of the liberal Temple Association (Tempelverband), Bruno Italiener, ("approved”), as well as to get a razor ("approved”). The transfer from the community cell and Rabbi Italiener’s request in Apr. 1938 to be allowed to donate money to Tachau were refused. From May to July 1938, Tachau tried several times to obtain permission to order a Danish textbook ("refused”).

In Sept. and Oct. 1938, he asked Bruno Italiener for assistance with his emigration ("approved”); in Nov. 1938, his civilian clothes were repaired at personal expense after checking his cash holdings. It is possible that the approvals, which became more frequent at the end of the prison term, were favored by Tachau’s "advancement to stage II,” following a positive assessment by the foreman and the supervising officer. Harald Tachau was released on 9 Dec. 1938. Bruno Italians himself emigrated to Britain in Jan. 1939 with his wife and children, thus being unable to continue supporting Harald Tachau.

In July 1939, in the course of compulsory labor for unemployed Jews in the German Reich, Harald Tachau was forced to do excavation work and road construction in the "Sprakebüll Jewish labor camp, District of Südtondern.” The Department of Labor Welfare of the Hamburg Welfare Administration sent Jews to perform "welfare work” ("Unterstützungsarbeit”), in cooperation with the Nordmark Employment Office, doing so also to special camps outside Hamburg.

In this context, Harald Tachau met the non-Jewish wife of a Jewish merchant from Neumünster, who had been committed to the camp by the Neumünster Employment Office in Jan. 1939. On 3 Oct. 1939, he was therefore placed in pretrial detention again. Until then, he had lived as a subtenant of Mrs. von Walther at Neue ABC-Strasse 12a (Hamburg-Neustadt). His state of health deteriorated in pretrial detention, a stomach ulcer was diagnosed, and in Mar. 1940, he had to be transferred to the prison hospital twice.

The new charges were for "racial defilement” ("Rassenschande”). Neither the case file nor the grounds for the judgment contain any information as to who had denounced the "Aryan” wife of a Jew and Harald Tachau or where the information about their relationship originated. Harald Tachau denied his Jewish descent (even to protect his brother Walter, who had been arrested in Apr. 1940 and had not disclosed his Jewish descent). Although the investigation revealed only a few physical advances on both sides, on 21 June 1940 the Hamburg Regional Court (Landgericht), "Sixth Criminal Chamber” (Strafkammer 6), presided over by regional court judge (Landgerichtsrat) Hermann Wehlen (presiding judge), regional court judge Bernhard Behr (associate judge), and regional court judge Werner Roscher (associate judge, not a member of the NSDAP) imposed a sentence of three years in prison.

Judge Hermann Wehlen (1903–1969), a member of the NSDAP and the SA since 1933, had also been a member of the legal staff of the Gau court (Gaugericht) of the NSDAP ("party court of honor”) since 1939. In July 1941, he changed to the Hanseatic special court (Hanseatisches Sondergericht) as a judge, where he was responsible for five death sentences. Bernhard Behr (born in 1900), also a member of the NSDAP and the SA since 1933 as well as of other Nazi organizations, had been transferred to civil justice since June 1934 because of an overly mild sentence. With stereotypical and partisan formulations, the jurists documented their linguistic and moral connection with the Nazi system in the grounds for the judgment: "The defendant dared as late as 1939 to indecently assault an Aryan woman, even if she was married to a Jew.” Regional court judge Walter Tyrolf (1901–1971) took part in the trial as a public prosecutor. He had been transferred from his position as investigating judge to the public prosecutor’s office only at the beginning of June 1940.

On 11 July 1940, Harald Tachau was transferred to the Fuhlsbüttel prison. Instead of being released after the end of the prison term in Oct. 1942, however, the following was noted in the file: "Release via the Hamburg criminal investigation department, transfer to a protective custody camp.” As early as Aug. 1940, Harald Tachau had contacted the Relief Organization of Jews (Jüdischer Hilfsverein) several times for assistance with the planned emigration. In Sept. and Nov. 1940, he also wrote to Carlos Feder (Sao Paulo) in an effort to find a way to emigrate to Brazil. Carl Feder (1882–1969), sole owner of the Wegner & Co. men’s underwear factory since 1922, had emigrated there in 1936. His son Erwin Feder (born on 18 July 1910) was imprisoned from 1938 to 1942 in Bremen and finally in Hamburg-Fuhlsbüttel for "racial defilement”; he died five weeks after his deportation in Jan. 1943 in Auschwitz (see www.stolpersteine-hamburg.de). Harald Tachau and Erwin Feder probably knew each other from Fuhlsbüttel prison.

The conduct reports of the station official in prison about Harald Tachau were positive ("conduct: very good, work: always exceeded his work quota”), for which he was allowed to send additional letters from prison in addition to the monthly letters ("granting or revocation of permissions and acts of faith”). However, all this was of no use to him, because Heinrich Himmler, Reich leader (Reichsführer) SS and chief of the German police, had already ordered in July 1940 that convicted homosexuals should be taken "into preventive police custody after their release from prison.” In Oct. 1941, the Nazi state had also prohibited the emigration of Jews from Germany and decided to deport and destroy them.

In May 1942, Harald Tachau wrote an approved special letter to the Relief Organization of Jews, two months later one to the "Auswandererberatung Scharlach,” an advisory office for emigrants, because of the imminent "evacuation” upon his release in Oct. 1942. At that time, Fritz M. Scharlach (1898–1943) was already detained in the Fuhlsbüttel concentration camp; his business was forcibly deleted from the company register in July 1942. Neither the Relief Organization nor Scharlach were able to help Harald Tachau.

The Fuhlsbüttel penitentiary informed the criminal investigation department and the state police headquarters of Tachau’s release date two months in advance. On 19 Nov. 1942, he was deported to the Auschwitz extermination camp. According to an entry in his Jewish religious tax (Kultussteuer) file card of the Jewish Community, he died there on 30 Jan. 1943.

How did his brothers Walter and Hans fare?
Harald Tachau’s brother, the lawyer Walter Tachau (1897–1974), had converted to the Lutheran faith in May 1915 during a military hospital stay. As a pupil of the Heinrich-Hertz-Gymnasium, he had joined the Hamburg 76th Infantry Regiment as a war volunteer at the beginning of Sept. 1914. Following demobilization in Dec. 1918, he joined the "Freikorps Bahrenfeld,” a paramilitary unit commanded by Lettow-Vorbeck, at the beginning of 1919. After studying law in Heidelberg and Hamburg, he ran a law firm together with his father from 1925 to 1929, and after his father’s death, he shared an office with Willi Gottberg (1898–1965) from 1929 to 1933. In the course of bankruptcy proceedings against his father, Walter Tachau was called in as guarantor, which burdened him "in way hardly bearable,” as the "court assistance for adults” (Gerichtshilfe für Erwachsene) of the Hamburg District Court noted in 1931.

Walter Tachau had concealed his Jewish descent from the state organs of Nazi Germany. Until his arrest on 12 Apr. 1940, he was therefore able to work as a lawyer, which would otherwise have been forbidden to him as of 30 Nov. 1938. He lived in a "mixed marriage” ("Mischehe”) with a non-Jewish woman.

In Apr. 1939, he defended the former HSV president Emil Martens (1886–1969), who had been a member of the club since 1907 and had served as president from Feb. 1928 to Jan. 1934. Martens had been officially dismissed by the sports authorities as club president in 1934 for violating the amateur statute that prohibited payment of money to league players. In 1936, Martens was convicted of homosexuality and expelled from the NSDAP; in 1939 and 1942, further charges were brought by prosecutor Nicolaus Siemssen (born in 1901, since 1929 prosecutor in Hamburg, since May 1933 NSDAP member). Walter Tachau himself had been a member of the HSV since 1910, active in soccer, track and field, and handball (HFC 88), and at the end of the 1920s, he was a board member of the club. Moreover, in 1929, he founded the Ochsenzoll-Norderstedt e.V. sports field association together with Emil Martens.

Walter Tachau was taken to the Fuhlsbüttel concentration camp on 23 Apr. 1940 and transferred to the Fuhlsbüttel prison in May 1940. In Sept. 1940, he was sentenced to three years in a penitentiary, which was converted into a prison sentence in Apr. 1941. The NSDAP genealogical officer (Sippen-Referent) of District 6 prepared a genealogical table specifically of the Tachau family for the racial evaluation of the defendant.

At the end of Aug. 1942, Walter Tachau was released from Glasmoor prison because his wife was seriously ill. He was ordered to report to the police twice a week. In Oct. 1943, the SS arrested Ernst Drescher, the chief public prosecutor and friend of Walter Tachau, who had granted prison leave and kept the criminal files in his custody. Out of fear of being arrested again, Walter Tachau fled hastily and without papers to southern Germany and on to Austria. There he survived with forged papers under the name of Dr. Curt Schröder in Vienna and Innsbruck, while a warrant was issued for his arrest. His wife Ilse had to divorce him under pressure from the Gestapo.

In Aug. 1945, Walter Tachau regained his license to practice as a lawyer. The HSV appointed him an honorary member.

Harald Tachau’s brother Hans, doctor of medicine (1901–1969), had written his medical dissertation, Die Beeinflussung des eosinophilen Blutbildes durch Infektionskrankheiten mit besonderer Berücksichtigung der Malaria ("The influence of infectious diseases on the eosinophilic blood count with special consideration of malaria”), at the University of Munich in 1926 after studying there. In 1930, he took over a medical practice including equipment for 10,000 RM in Hollenstedt (District of Harburg), approx. 10 kilometers (some 6 miles) south of Buxtehude. The Nazi regime withdrew his license to practice as a statutory health insurance physician and the right to treat staff of the Reich Railway Company (Reichsbahn). After an invitation to tender in the medical newsletter for 1 Apr. 1938, Friedrich Lummerich (born in 1908 in Osnabrück, doctorate 1936 in Freiburg/Breisgau, died in 1948) was appointed in his place as a general practitioner, who from Oct. 1938 was also assigned Hans Tachau’s apartment. For Hans Tachau, there was no longer any institution within the Nazi "German national community” ("Volksgemeinschaft”) that could help him in this situation to enforce his rights. He did not even receive a symbolic compensation payment for his medical practice.

Hans Tachau also lived in a "mixed marriage” with his non-Jewish wife Elisabeth (1909-2001), whom he had married in 1930. On 4 May 1938, the couple and their son moved in with her parents in Hamburg, who lived on Alsterdorfer Strasse, and six months later, they emigrated to the USA on board the "S.S. Bremen.” There Hans Tachau joined the US Army (Branch Immaterial - Warrant Officers) in Sept. 1942 as a "private.” In 1943, he became a US citizen. From 1946 onward, he practiced as a physician in Prattsburg/New York.
