The memorial plaque commemorating Péter Renner, Imre Sörös and László Zsigmond was installed on the outer wall of the Corvin Cinema in 1991. The black granite plaque designed by László Boroviecz was initiated by the International Federation of Certified Hungarian Freedom Fighters. It depicts the emblem of the Federation and bears an inscription. Péter Renner was born in Brno (formerly Czechoslovakia, today the Czech Republic) on March 20, 1933. His father was a bank director, his mother was a Hungarian of Jewish ancestry. The parents had been separated since the beginning of the 1940's. The mother was able to survive German occupation, although the entire maternal side of the family was murdered. After the liberation of Czechoslovakia, the family fled to Hungary due to increased discrimination. At the end of the 1940's, the mother emigrated to Great Britain, while Péter Renner remained in Hungary. In 1951, he obtained his higher education qualification in Esztergom and began an apprenticeship as a cartographer. He was called up for military service in 1953, but was sentenced to six months imprisoned by a military court on the charges of betraying confidential information. After completing his term of service, he was once again sentenced to imprisonment by a Budapest court on the grounds of monetary fraud. After the outbreak of the Revolution on October 23, 1956, Renner took part in the demonstrations and was present when the Stalin monument was toppled. In the industrial centre Csepel, he distributed the flyers of the insurgents to the workers. The Hungarian Secret Police ÀHV arrested Renner on October 24th. He remained incarcerated until October 29th, during which he was mistreated. After his release, he joined forces with the insurgents in the Corvin Passage. Renner functioned as an mediator between the Corvin köz insurgents and the National Guard. After the renewed invasion of Soviet troops, Renner continued the armed resistance with other comrades until November 9th. On November 26th, he managed to escape to Austria. There, Renner established contact with the Hungarian Revolutionary Council (Magyar Forradalmi Tanács) under the leadership of Lajos Várfali, and the latter gave Renner the mission of returning to Hungary in February 1957. His task was to be the establishment of contact with Workers' Councils and the families of those executed and imprisoned. Shortly before his planned return to Austria, Renner was betrayed and arrested. A military court condemned him to death on October 31, 1957. The judgment was affirmed by the Special Senate of the Military Collegium of the Supreme Court on February 3, 1958, and carried out two days later. The biographies of Imre Sörös und László Zsigmond could not be researched.
