Before the end of the Austro-Hungarian Empire single entrepreneurs built and ran power stations, most of which were fired with coal as this was a cheap resource in the empire. But after the end of World War I and the break-up of the Austro-Hungarian Empire in 1918 the Austrian First Republic suffered a serious economic set back and a shortage of energy. While the consumption of electricity was rising, coal had to be imported for running the coal-fired power stations. That’s why the construction of hydroelectric power plants was boosted in order to avoid the import of expensive coal from Silesia and Bohemia. Between 1924 and 1930 the newly founded federal state corporations realised the first water power projects despite the resistance of large Austrian banks which refused to finance these projects because they held shares in the huge Czech and Polish coal mines. At the same time the establishment of an interconnected distribution system of the independent federal states’ electric corporations was attempted. So in the 1920s and 1930s a shift from coal to water power was visible. Yet due to the separate interests of the nine different federal states a functioning Austria-wide interconnected electrical grid could not be established.

Even before the “Anschluss” in March 1938 (the incorporation of Austria into Hitler’s “Third Reich”) Germany was trying to get access to the largely unexploited water power resources in Austria. Hydroelectric power stations in the west of Austria already delivered electricity to Germany before 1938. In preparing for the next war Germany made the decision to expand water power production considerably and to centralise the whole electricity production. The “Energiewirtschaftsgesetz” (energy production law) of 1935 made all energy production subject to state planning. Due to the substantial increase in arms production the demand for energy dramatically rose in Germany. There most power stations were coal-fired. That’s why the economic arguments for integrating Austria into the German territory did not just include the extensive Austrian gold and currency reserves, metallurgical resources and production and the skilled human capital, but most of all the opportunities for the exploitation of hydroelectricity. In April 1938 Hermann Göring stressed that the development of the Austrian hydroelectric capacities was not in the interest of the Austrian population or economy, it served the purpose of the German preparation for war. Due to the decisive lack of energy in Germany, the National Socialist (NS) economic planning saw to it that immediately after the “Anschluss” all plans for hydroelectric power plants which had been designed before 1938 were put into practice. This constituted part of the NS “Four-Year Plan” in order to compensate the scarcity of energy in Bavaria and prepare for the establishment of a chemical and metallurgical industry there. Another project was the creation of an interconnected electricity grid which linked Austria to Germany, whereby the west of Austria was completely subjected to the needs of the German weapons production. That’s why 62 per cent of the newly established hydroelectric power plants were situated in Salzburg, the Tyrol and Vorarlberg. All energy production in Austria was centrally planned in Berlin and became part of the state-owned VIAG (“Vereinigte Industrieunternehmungen AG”). This organisation founded a subsidiary, the AEW (“Alpenelektrowerke AG”), which was responsible for the construction of hydroelectric power stations in the Alps and for building up an interconnected and coherent electricity grid. Local energy producers tried to resist, especially in the Tyrol, but to no avail. Yet all attempts at increasing production and capacity during the Second World War could not alleviate the energy shortage in Germany. Already before the war the industry was by far the largest consumer of energy and this trend was further intensified during the war. Until the beginning of 1942 the German energy production somehow managed to meet demand, but afterwards drastic restrictions were imposed on private energy consumption. Nevertheless, the German supply of electricity remained permanently insufficient and could no longer even meet the demands of the weapons production.

Another economic aspect of the “Anschluss” was the integration of half a million unemployed Austrian workers in German infrastructure projects and arms production, which had suffered under a lack of labour force since 1936. In the first period from the “Anschluss” in 1938 until the outbreak of the war in 1939 not only the unemployed were integrated in the German labour market, but slave labour was already introduced by applying the Nazi racist ideology and compelling the now marginalised population groups, most of all the Jews, Roma and Sinti to forced labour. During the second phase from 1939 until the military disaster of 1941/42 in the Soviet Union the employment of foreign forced labour started with foreign civilians who were forced to work in the German arms production and with prisoners-of-war. At the end of this period the German industry was so dependent on foreign forced labour that without it the war could not have been carried on. The third period from 1941/42 until 1945 was characterised by massive exploitation of Jewish and foreign slave labour. Slave labour in the Nazi period must not be confused with fatigue duty of citizens of the “Third Reich”, for instance of young women who had to work in agriculture for a year or for youngsters under the conscription age to construct motorways or defences (see article on “Nazi Children Evacuation Programme”). All forced labourers were racially or politically persecuted and subject to maltreatment after their home country had been conquered by the Nazis.

The various groups of forced labourers were treated differently by the Nazis. In Austria around 20,000 Jews were constringed to do slave labour after they had been excluded from the normal job market and the “Ostmark” (Nazi name for Austria) acted without a legal basis and as model for the rest of Germany with respect to brutal exploitation and expropriation of the Jewish population before their extermination in concentration camps (“KZ”). My great-grandfather, Ignaz Sobotka, was forced to do slave labour at the road construction firm “Teerag” and my grandmother, Lola Kainz, worked in the war-related industry in Vienna (see article “Nazi Collection Camps in Vienna”). Roma and Sinti were taken from their work places and locked up in forced labour camps in Austria before being murdered in the KZ Kulmhof and Auschwitz. The GESTAPO further ordered “unruly” German nationals and foreigners to be interned in so-called “labour education camps” (“Arbeitserziehungslager”) for some weeks or months before they were allowed to return to their work places. Another group of slave labour were around 50,000 Hungarian Jews who were chased to Austria from Budapest on foot after an agreement between the SS and the Hungarian Fascist representative Rezsö Kasztner in June 1944. They were interned in camps and compelled to work as slave labourers. The conditions in these camps in Austria were so terrible that a majority of the prisoners died within a very short time. Just to give two examples: in the camp in Felixdorf of 2,087 prisoners 1,865 died within a few weeks; in Lichtenwörth 1,600 out of 2,500 and in Gmünd 486 out of 1,700. When the Soviet army was approaching, those who were still alive were chased in “death marches” towards the KZ Mauthausen and Gunskirchen in the west, whereby 15,000 to 18,000 died.

Already at the end of 1939 the first prisoners-of-war arrived in Austria and they formed the second largest group of forced labour. According to military rank and nationality they were treated differently, whereby the Soviet prisoners-of-war were always treated worst; they were even systematically murdered. Most of the prisoners-of-war were used in agriculture, but also in factories and for the construction of dams and power plants. How many people died in POW camps and forced labour camps in Austria is unknown but the lowest estimate is 23,039; 96 per cent of which were Soviet prisoners-of-war. This number does not include those prisoners-of-war who died in the KZ network of Mauthausen, where more than 10,000 Soviet prisoners-of-war were murdered. Furthermore this number does not include the prisoners-of-war who died on death marches at the end of the war, when POW camps in the east of Austria, for example in Kaisersteinbruch, Gneixendorf and Edelbach, were evacuated and the prisoners chased west towards Braunau.

The KZ Mauthausen / Gusen near Linz was established in 1938 and starting as an extermination camp with a huge quarry developed in the course of its existence to a large network of concentration and extermination camps with an intricate system of division of labour, which ended fatally for tens of thousands of prisoners until the Allied liberation in 1945. Like many concentration camps the function of the KZ complex of Mauthausen / Gusen was extended from a death camp, whose only function was the killing of those interned there, to a forced labour camp in 1943 due to the drastic labour shortage in the German productive war industry. This meant that the number of KZ prisoners rose from 14,000 at the beginning of 1943 to around 73,000 in October 1944. The focus of employment of these KZ prisoners was the arms production in Linz, Steyr and Wels, for example the companies “Steyr-Daimler-Puch AG” and the “Reichswerke Hermann Göring” in Linz, and the industrial area around Vienna, for example “Henkel Schwechat”, “Flugmotorenwerke Ostmark” (aero engine maker) in Wiener Neudorf or “Rax-Werke” in Wiener Neustadt. The KZ complex Mauthausen /Gusen comprised more than 40 forced labour camps and the prisoners did not only work in the war-related industry, but also in the construction industry for the infrastructure development, such as tunnels and power stations, and finally since autumn 1943 in the construction of a huge network of tunnels to transfer the arms production underground. KZ prisoners had to dig tunnels for example near Melk for “Steyr-Daimler-Buch AG” and the “Flugmotorenwerke Ostmark”, in Ebensee for the development and production of rockets and in Gusen for “Messerschmitt” planes. At least 102,000 prisoners died in the KZ complex Mauthausen.

This map shows the ghettos and concentration camps the Nazis deported the Jewish population to from the collection camps in Vienna via the “Aspang” train station

The list with the dates and destinations of the 47 transports from the Aspang train station to ghettos and concentration camps 1939, 1941/1942. My great-grandparents Ignaz and Rudolfine Sobotka were to be deported on the 28 July 1942 to Theresienstadt, but then their transport was postponed to 13 August1942

The famous Viennese artist, the painter Arik Brauer, reported in an interview that a school mate and friend of his had come running to his flat in the 16th district of Vienna, Ottakring, when they were both around 13 years old, telling Arik that the next day he and his family had to report to the Nazi authorities in a collection camp in the 2nd district. He wanted his friend to have his collection of books by Karl May, a very popular adventure book writer of the time, because he was not allowed to take the books with him and he wanted to say good bye to Arik, too. Arik asked him why he did not run away and his friend answered, “Where shall I run to?” At that time no one believed that this transfer to the collective camps (“Sammellager”) in Vienna, also euphemistically called “collective flats” (“Sammelwohnungen”), led straight to the extermination camps of the Nazis. The former chief rabbi of Vienna, Chaim Eisenberg, told the story of his father who had survived in hiding as a “U-Boot”: he had never laughed so much in his life as during these terribly trying times. Jewish humour kept them alive and helped them not to give up hope. But many could not bear the humiliation and terror and committed suicide. More than 130,000 people could flee before the complete ban of emigration of Jews in October 1941. Yet around 17,000 of those were caught up by the Nazi terror machine in their countries of refuge, such as France, the Netherlands and Belgium. In the years 1941/1942 45,527 persons were hauled from the Viennese collective camps via the “Aspang” train station in 47 transports to ghettos and concentration camps in the “East” (as the Nazis called the occupied territories in Central and Eastern Europe), among them my great-grandparents, Ignaz and Rudolfine Sobotka. They were interned in a collective camp in Krumbaumgasse 6/14 in the 2nd district of Vienna on 9 July 1942 before they were deported to the ghetto Theresienstadt (today Terezin) on 13 August 1942. They were liberated after three years of imprisonment by the Allied Forces on 7 July 1945. Of the 1,634 people who are recorded as “U-Boote” in Vienna 1,000 survived more than one year in hiding, more than 400 attempted to survive in hiding, but were discovered before disappearing successfully and were deported. All in all 66,000 Austrian Jews were murdered in the Shoah and Vienna became a model for the organisation of Nazi terror and the extermination of the Jewish population, which was later copied in the rest of the German “Third Reich”.

The postcard my grandmother Lola Kainz sent to her parents in the collective camp from their mountaineering holidays in the Großglockner region in Salzburg
“Dearest parents, We are great. Herterl (my mother) is a sweet and good girl and looks great. The food is wonderful here. Unfortunately the weather is not too good. Herterl has just written to her teacher. Hopefully everything is ok. Many kisses Herta. Thousand kisses Lola and Toni”

The postcard my grandfather Toni sent them from the same holiday from Zell am See
“We are already far away from Zell am See. At the moment we are in Salzburg in the region where I worked three years ago; refreshing memories; most of all we are looking for warmer weather. In Krimml we already had 10 cm of snow. Otherwise we are doing fine; we are shovelling food from morning till evening. Herta has put on weight and eats a lot. Greetings and kisses Toni. Many kisses, yours Lola. Many kisses, yours, Herta.”

The content of the two postcards, which were sent to Ignaz and Ritschi in the collective camp by their daughter Lola and their son-in-law Toni, support the statement of Arik Brauer that the families were not aware of the deadly seriousness of the GESTAPO orders to report at the collective camps and that the stay there was just a transition to the deportation to ghettos and concentration camps. But the banality of the reports about holiday experiences, food and weather in Salzburg might also have been intended to boost the morale of the parents and to sound positive, optimistic and hopeful. Ignaz and Ritschi never talked about their experiences during the time of imprisonment from 9 July 19242 until 7 July 1945. That’s why it is so important to research this dark period of Viennese history now in times of rising anti-Semitism in an attempt to prevent similar disasters in future, because as the writer William Faulkner once said, “The past is never dead. It’s not even past.”…


The “Viennese Diary of 1944/1945” by Josef Schöner (1904-1978) offers a personal impression of the life in the city of Vienna during the last days of the war and the months after the liberation of the city by the Soviet Red Army. Schöner was an Austrian diplomat who had been dispatched to the United States and was forcibly retired by the Nazis in 1939 after the “Anschluss” (the Nazi takeover of Austria). During the war he worked in the restaurant business of his parents and was called back to diplomatic service after the end of the war. The experiences of my grandparents, Lola and Toni Kainz, and their daughter, Herta, my mother, are an important source of information about life in Vienna during the last months of the 2nd World War and the time after liberation. My great-grandparents, Ignaz and Rudolfine Sobotka, in the photo below with Lola, their daughter and Herta, their granddaughter, returned from the Nazi concentration camp Theresienstadt to Vienna in the summer of 1945, but they never talked about their experiences during their imprisonment.

This article furthermore deals with the way restitution worked for the victims of Nazi persecution after the war, focussing on the non-elite who had survived Nazi concentration camps and the ordinary Viennese citizens of Jewish descent who returned from exile. The overall number of those who came back to settle in Austria again was embarrassingly small: only 6 per cent. This can be explained by the fact that they were not at all welcome in post-war Austria.

The decision of the Allied Forces in 1943 to insist on “unconditional surrender” of Germany implied that Germany would have no say at all in the new world order after the end of the 2nd World War. The Allies then started to discuss the destiny of the many small states which had been incorporated into the Nazi “Third Reich”. Austria was just one of them and certainly not the most important one. A new order in Central Europe was considered important because it had become apparent that the Western inter-war policy of the 1920s and 1930s had failed in the region. The British were the first to weigh the pros and cons of four different options for Austria after the end of the war.  First, Austria could become an independent state as between 1918 and 1938; second, it could remain in a union with Germany; third, Austria could be part of a new, not yet clearly defined “Danube Confederation” or fourth, Austria could be split up and the western part would join Germany or Switzerland and the eastern part the “Danube Confederation”. But the Soviet Union had its own interests in the Central European region and Stalin insisted on the restoration of an independent Austrian Republic. The British wanted to boost the resistance among the Austrians against the Nazis and made that a condition for a preferential treatment of Austria after the victory over Nazi Germany. They were certain that Austria had to rely on massive foreign aid to survive as an independent state and that’s why they preferred a “Danube Confederation”. But the Soviets were strictly against any form of a Central European confederation of states. At the same time there was no clear strategy visible in the USA and the British did not want to alienate either the Americans or the Soviets. In a draft of July 1943 Austria was declared the first free country which had been a victim of Nazi aggression and the decision how Austria would be treated in future would depend on the behaviour of the Austrian people, who were responsible for the war, too. The “Anschluss” was imposed on Austria and was therefore null and void. In order not to become a basis for German aggression again in future Austria was to be restored as an independent state. Already in this draft the responsibility of the Austrians for the war was deliberately expressed in an ambiguous way. At that point in time also the governments of the Commonwealth countries discussed the destiny of small European states like Austria and the South-African Prime Minister Jan Smuts vehemently opposed a promise to Austria that it could expect preferential treatment to Germany and he further rejected the idea of promising independence to small states which were economically too weak to survive. He pleaded for a South German state, which would achieve two goals, namely a breaking up of Germany and the integration of Austria in a state with Bavaria. This was a solution which did not please the British Foreign Office under Anthony Eden who preferred a Central European Confederation and refused to offer preferential treatment to Bavaria, the region of origin of National Socialism. The Soviet Union pleaded for the Austrian independence and stated that they would not expect Austria to come under the Soviet sphere of influence.  Interestingly, the Soviets did not want to stress Austria’s responsibility for the war.

Finally on 1 November 1943 the “Moscow Declaration” confirmed that Austria was the first victim of Nazi Germany and would be restored as an independent republic once Hitler was defeated. At that point in time it was not to be predicted of how great the importance of this document would be for the future of Austria in 1945. Despite its ambiguity this declaration is the most important document for Austria before the State Treaty of 1955. The “Moscow Declaration” must have been known in Austria in November 1943 because the Nazi newspaper, the “Völkischer Beobachter”, reported about it. In conclusion it can be said that the British had invested much more thought in the future of Austria than any other of the Allied partners. They now started to plan the zones of occupation after the war and were prepared to offer the whole of Austria to the United States because their projected zone of occupation in southern Germany was rather small. But the Soviets insisted on a joint occupation of Austria by the Soviets, the Americans and the British. During this time of strategic planning, the war continued and the destruction of the German and Austrian cities and infrastructure was stepped up by Allied bombardments. In the spring of 1944 the south of Austria had come under attack of Tito’s Communist Partisans from the south. In September 1944 Churchill and Roosevelt agreed on the zones of occupation for Germany and the Soviet, British and American diplomats came to an understanding that the one who reached Vienna first, would invite the other two Allies to join in. On 31 October 1944 the British stipulated what should happen in case Austria was reached by the Allied troops before the unconditional surrender of Germany. Most importantly these directives included a warning that Austria could not escape its responsibility for the participation in the war and that it would be held accountable. Yet the degree to which Austrians contributed to the liberation of their own country would be taken into account. This proclamation stated that the British considered Austria an enemy state because Austria was waging a war against the Allies and that’s why the British considered themselves as victors and not liberators. The Soviets wanted to occupy the Burgenland and the eastern parts of Lower Austria and Styria and a third of the city of Vienna. The Americans expected that their zone of occupation in Vienna included an airfield. Basically, the Americans and the French had no special interest in occupying parts of Austria. Their focus was on Germany, but they accepted the British invitation to participate in the occupation of Austria.


After the “Anschluß”, the takeover of the Nazis in Austria on 12 March 1938, the racial background of every citizen was documented according to the Nazi Nuremberg race laws and my mother, Herta, was classified as a “Mischling 1.Grades” (a “mixed race child of the 1st degree”) – as can be seen in the documents above. Her mother, my grandmother Lola (Flora Kainz), was a Catholic of Jewish descent with Jewish parents, my great-grand parents Ignaz and Rudolfine Sobotka, which meant that all of them had to bear the full brunt of racial discrimination of the Nazi dictatorship. But as long as my grandfather, Anton Kainz, the father of Herta, stood by his family and did not divorce my grandmother Lola, at least Lola and Herta were somehow “protected” because he was a certified “Aryan”. But this “protection” was constantly on the brink of being withdrawn, despite the fact that Toni loved his wife dearly and adored his daughter and would never have thought of giving in to Nazi pressure. This constant insecurity and permanent racial discrimination left deep scars especially in the psyche of Herta, who was four and a half years old at the time of the “Anschluß”. She first lost her aunts and uncles who had to flee Austria, then her grandparents, who were deported to the KZ Theresienstadt and then was in constant fear that her mother would be arrested and deported, too. At the end of the war she was eleven and a half and was not only terribly afraid of the Allied bomb attacks on Vienna, but even more of the knocking on the door and a surprise visit of the GESTAPO which would take away her mother. It was impressed on her by her father that she had to run to the fish shop where he was the branch manager and inform him immediately if anything happened to Lola. Herta remembered that her parents had lots of friends and kept in contact with them during the Nazi occupation. One of them was a high-ranking NSDAP party member and he proposed that Lola should hide in his flat in case of emergency, because no one would suspect him of secretly protecting a Jewess, so she would be safe at his place. But fortunately this was not necessary. Till the end of her life this fear accompanied Herta. Despite the tragic political circumstances and the discrimination she faced as a child, she stressed what a happy childhood she had had because her parents doted on her and this love carried her through those hard times – and the close friendship to a girl who lived in the same house in Mariahilferstrasse 41 and was an outcast just like her. Her name was Herta, too, and she was a very unruly foster child. This unlikely couple, the extremely timid and withdrawn Herta, my mother, and her daring wild playmate remained friends until old age despite the fact that their lives took very diverging paths: My mother became a master dressmaker and “the other” Herta a bar singer. Maybe the discrimination they faced as children created a lasting bond.

The fate of Jewish partners in “mixed marriages” and of “Mischlingskinder” (“mixed race children”) in Vienna was a doubly tragic one because after the war their sufferings were not recognised, neither by the 2nd  Austrian Republic nor by the Jewish or Catholic community with the argument “nothing had happened to them – they had survived”. Yet the fast succumbing to a very severe form of dementia at a rather early age can be contributed to the trauma Herta had experienced during the Nazi occupation and that had never been diagnosed or treated. It seems that children carried these traumas with them all their lives and despite apparently functioning very well as adults, the harm that was done to their souls came up again much later in life once more.

All Jewish women were forced by the Nazis to take on the name “Sara”, as can be seen in this document of the 30 June 1939 of my grandmother Flora Kainz, called Lola. Jewish men had to include “Israel” in their names.

“Ariernachweis” (“Aryan Certificate) of Anton Kainz, Herta’s father. This document proved the “Aryan” status of Toni, which provided some fragile protection for Lola and Herta. The handwritten addition stated that Toni was married to a Jewess.

The Nazi IDs of Toni (left – the Nazi eagle was covered, probably because the ID was still in use after the liberation by the Allied Armies) and of Lola (right – marked with a “J” for Jewish)

If this photo of Lola of 1939 is compared to the photos of her before 1938 in the articles on classical music, suburban inns and suburban cafés on this research website, one can see that the happy-go-lucky beautiful young woman of those days had turned into a terrified, emaciated and desperate one within a year.

When Toni was drafted by the “Wehrmacht” for the campaign against France, he wrote this Christmas card to Lola from the front on the 24th December 1940 declaring his never ending love for her despite Nazi pressure to divorce her. He quoted the famous lines of the operetta aria “Das Land des Lächelns” by Franz Lehár: “Yours is my whole heart” on the front of the card.

The text Toni wrote, which was censured by the Army High Command, says: “Dearest Muckerle! All the best for the New Year. I only wish for one thing which is being together again very soon. Kisses, yours Toni”
