Heinrich Dalla Rosa

At Easter 1941, Heinrich Dalla Rosa expressed "doubts about a good outcome to the war" to Otto Hladnig, a former theologian from St. Lamprecht Abbey who had defected to the National Socialists. However, the latter does not pass on these statements for the time being. Around Christmas 1943, Otto Hladnig gave a lecture on the German Wehrmacht to the teachers' working group in which he spoke disparagingly about "Christ and Christianity". When Heinrich Dalla Rosa hears about this, he immediately goes to Otto Hladnig to complain. However, he only finds his heavily pregnant wife at his address. In a two-hour conversation with her, he later utters some problematic words.

Otto Hladnig informs representatives of the NSDAP about Heinrich Dalla Rosa's statements, who in turn inform the Gestapo. Heinrich Dalla Rosa was finally arrested by the Gestapo at 8:00 a.m. on August 23, 1944. Although the parish priest of Obdach informed the prince-bishop's ordinariate in Graz on the same day, the chief prosecutor did not inform the episcopal administration until three weeks later, on September 12, 1944.

In Vienna's Regional Court I, Heinrich Dalla Rosa awaits his execution. Both the family and the clergy, including the Archbishop of Vienna Theodor Cardinal Innitzer write tireless pleas for clemency. Unfortunately in vain. On January 24, 1945, shortly before the collapse of the unjust regime, Heinrich Dalla Rosa was executed by guillotine at 6:24 pm. The prince-bishop's ordinariate in Graz-Seckau was informed on January 26, 1945 and his parents on February 9, 1945.

On this day, a total of 11 men and 3 women are murdered by guillotine in Vienna's Regional Court I. The bodies of Heinrich Dalla Rosa and the other victims were taken to Vienna's Central Cemetery that night and buried in an anonymous mass grave (group 40). A church burial was refused.
