Born on 29 January 1903 in Vienna (Austria); disappeared in Barcelona (Spain), September 1937. Member of the Austrian Communist Party, then of various Left Opposition groups in Vienna, Berlin and Paris. Member of the POUM in 1936.
The son of a prosperous Viennese wine merchant, Kurt Landau had a Bohemian student youth similar to that of many young people from the Jewish intelligentsia in the imperial capitals: but it is also said that he attempted various circus jobs and for a time was a lion tamer at the Hagenbeck Circus. In 1921 this educated and cultured adolescent joined the new-born Austrian Communist Party, already shaken by fierce factional struggles and in 1922 became leader (Leiter) of the Warring district (Bezirk) in Vienna. Early in 1923 he supported the left-wing criticisms made by the Italian Bordiga  of the new line of the International, which was described as “opportunist”. In 1924, still in Vienna, he made the acquaintance of Victor Serge, who was part of a group of Comintern emissaries and who worked on its press bulletin Inprekorr.  It seems that Serge gave him the first solid items of information about the factional struggle in the USSR. The same year Landau took charge of the CP agitprop department and became an editor of its main publication, Die Rote Fahne (Red Flag), with responsibility for cultural matters. In the discussion on culture he adopted the arguments developed by Trotsky against “proletarian culture”.
Originally he kept aloof from the struggle between the two rival oppositions of Josef Frey and Karl Tomann, but he moved closer to them after their unification in September 1925. In March 1926 he joined this “united opposition” which he seems to have considered as the Austrian equivalent of the Russian United Opposition.  Expelled along with most of his comrades in late 1926, he was, in early 1927, one of the founders of the Kommunistische Partei Oesterreichs-Opposition (KPÖ-O – Austrian Communist Party Opposition), led by Frey, which published Arbeiterstimme (Workers’ Voice). Originally he supported the view that the KPÖ-O should not work for the reform of the Austrian CP, but should itself aim to become the real Austrian Communist Party. However, the KPÖ-O continued to reproduce the fierce internal factional struggles of the Austrian Communist Party with its regroupments, its shifts of alliance and its bitter personal conflicts. Following a heated theoretical debate with Frey, Landau and some of those close to him were expelled from the KPÖ-O in April 1928 for an “ultraleft deviation” (according to the historian W Wagner , this involved sympathy for the ideas of Karl Korsch ). He then founded a rival organisation, the Kommunistische Opposition-Marxistisch-Leninistische Linke (Communist Opposition, Marxist-Leninist Left), whose support was based in the city of Graz, and he began to issue his own publication, Klassenkampf (Class Struggle), then Der Neue Mahnruf (The New Warning Cry).The conflict between Landau and Frey then reached new heights of invective and personal accusations. He met Rosmer at the station when he visited Vienna in July 1929, and made the best impression on him.  Trotsky and Rosmer considered transferring him to Paris to support Rosmer in international work. Landau, in an article which was reproduced notably in the publication of the Leninbund , Die Fahne des Kommunismus [The Flag of Communism], and then in Contre le Courant [Against the Stream] , supported Trotsky’s position against Urbahns  and Maurice Paz.  This marked the beginning of a correspondence with the exiled Russian. Impressed by the talent and clarity of expression of this young militant – Landau was only twenty-six – and anxious to get him away from the overheated factional culture in Vienna and make full use of him in work appropriate to his abilities and of enormous importance, Trotsky had no difficulty in persuading him to go and settle in Berlin with his partner (Katia Lipshutz had been living with him since 1923). Trotsky took responsibility for meeting his material needs out of the money he received for copyright in Germany.
Contact with the militants of the Leninbund sympathetic to Trotsky proved very difficult. Landau presented himself as a “representative of the Russian Opposition” – that is, of Trotsky – and seemed unwilling to allow any discussion. Seeing that the Leninbund did not offer him favourable ground, he turned to the small Berlin group known as the “Wedding Opposition”, which had been in contact with the Russian Opposition for a long time, and which was at this time led by the young Hans Schwalbach ; he was thus able to have his own political force at his disposal. It seems that Trotsky was not able to keep him to a path which no longer meant winning over the Leninbund, but rather splitting it; nor could he improve his relations with the German nucleus of veterans who made up the “Leninbund minority”. After the expulsion of the latter group, he came under renewed pressure from Trotsky and from the insistence of visitors to Constantinople, Pierre Naville  and Max Shachtman , to commit himself to progress towards unification; this was concluded on 30 March 1930 by the formation of the Vereinigte Linke Opposition (United Left Opposition – VLO) in the KPD (German Communist Party) Bolshevik Leninists, the German section of the International Opposition which was being built. As a member of the Executive of the VLO from its creation, and editor-in-chief of its publication Der Kommunist (The Communist), and elected a member of the International Bureau a few days later, Landau seemed destined to become one of the main international leaders of the Left Opposition – in fact he was only passing through. To begin with there was his unconditional support for his Austrian comrades in Der neue Mahnruf in their factional struggles and the excessive accusations made in support of their cause, and the political conflict with the Leipzig organisation of the VLO, being manipulated at this time by Stalin’s agent Ruvin Sobolevicius, who was using the pseudonym of Sobolev or Roman Well. Moreover his pursuit of international alliances was dubious in Trotsky’s eyes, and finally his own policy of removals from office, expulsions and forcible takeovers within his own organisation made a split inevitable. Landau’s opponents described him as a “psychopath” and insisted that no cooperation with him was possible because of his “methods”. The split was finalised on 31 May 1931, following the visit of Pierre Frank.  Kurt Landau then kept control of Der Kommunist, and transformed the faction of the organisation which he had kept under his control into the Linke Opposition der KPD/Bolshewiki-Leninisten (Left Opposition of the German CP/Bolshevik-Leninists). Its sole basis seems to have been a shared hostility to Trotsky’s “methods”. Landau, who still had good relations with Rosmer, was also in contact with the Gauche communiste (Communist Left) of Claude Naville  and Michel Collinet , and, it appears, with the Izquierda comunista (Communist Left) of Andrés Nin. 
The organisation led by Landau – at most three hundred members – continued clandestine activity in German until spring 1934 when it was destroyed by Gestapo infiltration and the arrest of militants. Kurt Landau had emigrated to Paris in March 1933 with Katia. He pioneered the denunciation of Trotsky’s “betrayals” and “capitulations”: this was how he described the latter’s orientation in 1933 towards “a new communist party” in Germany, then towards “a new international”, and subsequently his policy from 1934 onwards of “entrism” in the Socialist Parties and the “French turn”. From May 1933, he had printed in Vienna and published in Paris Der Funke [The Spark], organ of the Marxist-Internationalists, of which he was the main and often the sole member of the editorial team. But this paper was to be killed off in Austria in 1934. Henceforth Landau was reduced, in the words of Hans Schafranek , to “circle work”, and duplicated publications. Shortly after his arrival he had grouped around him a certain number of oppositional members of the Communist Party [PCF] who were in process of breaking with Trotsky, and he began to orient himself towards work inside the PCF. He considered that the Left Opposition had been destroyed by “Trotsky’s liquidationist current”, but insisted that it had “laid the ideological foundation for the oppositional tendencies of the future”; for him now the only perspective was “the struggle to win over politically the Stalinised vanguard of the proletariat” through the building of a clandestine “internal faction” capable of giving life to “spontaneous oppositional tendencies” within the PCF. On the basis of this line he made contact and merged with the small internal opposition group in the PCF led at this time by André Ferrat , a member of the Political Bureau, and the Pole Georges Kagan/Lucien Constant  who was in charge of agitprop. From 1935 Landau became one of the members of the nucleus and of the editorial team of the journal Que Faire? (What is to be Done?) published by the group in question, in which also participated the former oppositionists Pierre Rimbert  and Hipólito Etchebéhère and his wife Mika Etchebéhère. 
Landau began his collaboration with this review with a startling article entitled: From the Fourth International to the Second International. The Path which led Leon Trotsky to Social Democracy. In this he stated in particular: “Revolutionary Marxists must follow their own road both within the Party and in the Communist International. They must group together within the Party to help the Party and the International find the right road, Lenin’s road.” In September–October he published another article in Que faire?, a polemic against “comrade Bréval” (André Ferrat), who had cautiously envisaged the use of “defeatist” slogans in the event of a war in which the USSR was France’s ally. Landau, for his part, declared that everything should be done for the defence of the USSR, writing: “The defeatist slogan does not take account of this double and complicated problem: it is correct in the case of a war between two armed imperialist groups, but not for the Soviet-imperialist bloc, which is a bloc full of contradictions.”
Kurt Landau was profoundly shaken in August 1936 by the trial of the Sixteen in Moscow, following which Zinoviev, Kamenev and other old Bolsheviks were sentenced and executed. He tried to organise a joint protest in Paris by the émigré oppositional Communist groups, and he made vain efforts to convince Brandler, the leader of the KPO  and the leaders of the SAP.  He ended up merely with a joint action with the German section of the ICL , the IKD , and with the International Group of Ruth Fischer  and Maslow.  But he also polemicised against Trotsky and Sedov  and their opinion that the accused Olberg  was a GPU agent who had played the role of police spy in the trial. Olberg, a former member of the German Left Opposition, had followed Landau at the time of the 1931 split, and the latter preferred to see him as a victim of the GPU. On this occasion he entered into correspondence with the oppositional group in the Czech CP around Josef Guttmann  and Záviš Kalandra. 
After the relative failure of his attempts to mobilise action against the Moscow Trial, Kurt Landau turned to Spain where he saw an authentic proletarian revolution with the potential to regenerate the Communist movement. His friends Hipólito and Mika Etchebéhère had already gone there, and the former had died on the Madrid front. Landau arrived in Barcelona with Katia in November 1936. He rapidly won substantial influence with the leaders of the POUM which he joined – without abandoning his general strategy of “reforming” the Communist Parties. He contributed to La Batalla , and coordinated the POUM’s international relations, especially in connection with the preparation of the international conference in Barcelona being planned by the POUM leadership. He still envisaged “a new Zimmerwald” of which the POUM would be the axis, and in this perspective he drew up programmatic bases for the international regroupment which was to be created. This activity drew him into a sharp polemic against the Brandlerites and the SAP supporters, and particularly against the young Willy Brandt , who was at this time a defender of the Popular Front policy. But this battle of ideas against the supporters of the POUM “right” did not prevent him from presenting in his articles and pamphlets a defence and celebration of the POUM’s policy which formed a permanent and particularly sharp polemic against Trotsky and the Fourth International. Landau’s activity against the POUM could not fail to draw him to the attention of Stalin’s agents who knew that this militant did not enjoy any diplomatic protection. He had to go into clandestinity after the days of May 1937 and the outlawing of the POUM.  We do not know why he left the relatively safe shelter which the Catalan CNT  had obtained for him at the request of Augustin Souchy.  He lived for some weeks in the suburbs of Barcelona, at the home of a veteran woman activist of the Spanish opposition, the Izquierda comunista and the POUM, and it was there that he wrote in particular his article against Trotsky Bolshevism, Trotskyism and Sectarianism. The police or at least the Soviet intelligence services were actively looking for him: we know from the interrogations of other prisoners that he was accused of being a member of the Executive Committee of the POUM and the instigator of a “terrorist group” for which Stalin himself was a target. He was arrested on 23 September at the home of the POUM militant, Carlotta Durán, who was hiding him, by three policemen – two in plain clothes and one assault guard in uniform – who came at 7.30 p.m. Nothing more was heard of him. On 30 September, the General Delegate for Public Order in Catalonia, Paulino Gómez, officially denied that the police service had anything to do with his arrest. It is probable that he had been arrested by officers who were members of the intelligence services, or that he was immediately handed over to them and held captive in one of the “chekas”  that they controlled. Kurt Landau was never seen again. Neither protest movements abroad, nor the heroic efforts of his partner could shed any light on the route that led to his death. One version that circulated in the jails claimed that he had actually been tortured and put to death in the cellars of the Colón Hotel in Barcelona. Others say he had been seen in the premises of the cheka at 299 Corcega Street in Barcelona. Katia Landau did not rule out the possibility that he was taken to the USSR with a view to a “Moscow Trial”, and that he was executed there.
Kurt Landau’s partner, Julia Lipshutz, known as Katia (born in 1905), who shared his life and struggles from 1923 onwards, was arrested in Barcelona while he was in hiding; in prison she went on hunger strike from 8 to 22 November 1937 to demand information on her husband’s fate and to know whether she herself had been imprisoned with a specific charge or as a hostage. She was released following numerous representations made by French socialists, especially Marceau Pivert.  Remarried to Benjamin Balboa (1901–1976), the man who had enabled the crews of the Spanish fleet to forestall the officers’ rising in 1936, she emigrated with him to Mexico in 1940 and settled in Cuernavaca where she was still living in 1984.  She continued trying to cast light on the murder of Kurt Landau.
