Information:  - Friedrich Mandl ( 9 February 1900 -- 8 September 1977 ) was chairman of Hirtenberger Patronen - Fabrik , a leading Austrian armaments firm founded by his father , Alexander Mandl . A prominent fascist , Mandl was attached to the Austrofascism and Italian varieties and an opponent of Nazism . In the 1930s he became close to Prince Ernst Rüdiger Starhemberg , the commander of the Austrian nationalist militia ( `` Heimwehr '' ) , which he furnished with weapons and ammunition . From 1933 to 1937 , Mandl was married to Austrian actress Hedwig `` Hedy '' Kiesler , who would later become known as Hedy Lamarr in Hollywood . Both Hedy Lamarr 's parents were born Jewish , but her mother converted to Roman Catholicism and was a practicing Catholic . Hedy was brought up Catholic . It is understandable , considering the times that she lived in , that she kept her ethnicity a secret . The couple were rumored to have very intimate contacts with the very highest levels of the people controlling Germany . In her autobiography she indicates that she attended a convent school for girls . When she went to Hollywood her connections with very wealthy people were obviously helpful to her career . Her first `` serious '' film was Algiers for which she was highly acclaimed at the time . Mandl is rumoured to have attempted to bring a halt to her acting career in Germany and to purchase all copies of her infamous film Ecstasy ( 1933 ) , in which she appeared nude . Following incorporation of Austria into Nazi Germany with the Anschluss of 1938 , Mandl 's remaining property which had not yet been transferred to Swiss ownership was seized , since he had supported the separatist Austrofascism and his father was Jewish . Despite Mandl 's part Jewish heritage , his then - wife Lamarr wrote in her autobiography Ecstasy and Me , that both Italian dictator Benito Mussolini and German dictator Adolf Hitler attended Mandl 's parties .

In German-speaking countries the first so-called "Freikorps" "free regiments" were formed in the 18th century from native volunteers, enemy renegades and deserters, and criminals. These sometimes exotically equipped units served as infantry and cavalry or, more rarely, as artillery. Sometimes in just company strength, sometimes in formations up to several thousand strong, there were also various mixed formations or legions. The Prussian "von Kleist Freikorps" included infantry, jäger, dragoons and hussars. The French Volontaires de Saxe combined uhlans and dragoons.  - Engelbert Dollfuss (; October 4, 1892  July 25, 1934) was an Austrian Christian Social and Patriotic Front statesman. Having served as Minister for Forests and Agriculture, he ascended to Federal Chancellor in 1932 in the midst of a crisis for the conservative government. In early 1933, he shut down parliament, banned the Austrian Nazi party and assumed dictatorial powers. Suppressing the Socialist movement in February 1934, he cemented the rule of austrofascism through the authoritarian "First of May Constitution". Dollfuss was assassinated as part of a failed coup attempt by Nazi agents in 1934. His successor Kurt Schuschnigg maintained the regime until Adolf Hitlers annexation of Austria in 1938.  - Kurt Alois Josef Johann Schuschnigg (14 December 1897  18 November 1977) was Chancellor of the Federal State of Austria from the 1934 assassination of his predecessor Engelbert Dollfuss until the 1938 "Anschluss" with Nazi Germany. He was opposed to Hitler's ambitions to absorb Austria into the Third Reich.  - Austrofascism was the authoritarian rule installed in Austria with the May Constitution of 1934, which ceased with the annexation of the newly founded Federal State of Austria into Nazi Germany in 1938. It was based on a ruling party, the Fatherland Front ("Vaterländische Front") and the Heimwehr (Home Guard) paramilitary militia. Leaders were Engelbert Dollfuss and, after Dollfuss's assassination, Kurt Schuschnigg, who were previously politicians of the Christian Social Party, which was quickly integrated into the new movement.  - A paramilitary is a semi-militarized force whose organizational structure, tactics, training, subculture, and (often) function are similar to those of a professional military, but which is not included as part of a state's formal armed forces.  - Nazi Germany is the common English name for the period in German history from 1933 to 1945, when Germany was governed by a dictatorship under the control of Adolf Hitler and the Nazi Party (NSDAP). Under Hitler's rule, Germany was transformed into a fascist state in which the Nazi Party took totalitarian control over nearly all aspects of life. The official name of the state was "Deutsches Reich" from 1933 to 1943 and "Großdeutsches Reich" ("Greater German Reich") from 1943 to 1945. The period is also known under the names the Third Reich and the National Socialist Period (abbreviated as "NS-Zeit"). The Nazi regime came to an end after the Allied Powers defeated Germany in May 1945, ending World War II in Europe.  - Hirtenberg is a town of approx. 2,500 inhabitants near Baden bei Wien in Lower Austria, Austria. The river Triesting is located at the south border of the town. Coming from the Vienna Woods, the valley of Triesting joins the Vienna Basin here.  - The Heimwehr ("Home Guard") or sometimes Heimatschutz ("Homeland Protection") were a nationalist, initially paramilitary group operating within Austria during the 1920s and 1930s; they were similar in methods, organisation, and ideology to Germany's Freikorps. Although opposed to parliamentary democracy, the Heimwehr maintained a political wing known as the Heimatblock, which cooperated with Engelbert Dollfuss' conservative government. In 1936, the Heimwehr was absorbed into the Fatherland Front by decree of Chancellor Kurt von Schuschnigg and replaced by a militia supposedly less inclined towards uproar against the regime, the "Frontmiliz".
