Simon Wiesenthal was a man who spent his life seeking justice. 
During World War II, Simon faced many terrible hardships. He was a Jewish survivor of the Holocaust. He lived through the occupation of Lwów, which was a city in Poland. The Nazis forced many Jewish people into a ghetto. This was a small, crowded area where they had to live. Simon and Cyla were sent to the Janowska concentration camp in late 1941. He worked at a railway repair shop during this time. He survived several other camps like Kraków-Płaszów and Mauthausen. His family suffered greatly, and 89 of his relatives were killed.
After the war ended, Simon began a very important mission. He wanted to find Nazi war criminals who had escaped. He wanted these people to face a trial for their actions. In 1947, he helped start the Jewish Historical Documentation Centre in Linz, Austria. This center helped people find lost relatives after the war. In 1961, he opened another center in Vienna. He worked to gather facts and evidence for future court cases. His work helped make sure that the truth was recorded.
Simon was involved in several famous cases during his career. He played a small part in finding Adolf Eichmann in 1960. Eichmann was captured by a group called Mossad in Buenos Aires. Simon also worked with the Austrian government to find Franz Stangl. Stangl was sentenced to life in prison in 1971. In the 1970s, Simon spoke to the press about political leaders. He pointed out that some leaders had been in the Nazi Party. This work sometimes caused him trouble with powerful people.
Today, many people remember Simon for his courage and his search for truth.
Simon Wiesenthal was an Austrian Holocaust survivor, a dedicated Nazi hunter, and a writer. 
Wiesenthal's early life was shaped by movement and study. He was born on December 31, 1908, in Buczacz, which was then part of Austria-Hungary. His father, Asher Wiesenthal, was a wholesaler who had moved from the Russian Empire to escape pogroms, which were organized attacks against Jewish communities. After his father died in combat during World War I, Simon and his family moved to Vienna. Later, they returned to Buczacz. Wiesenthal developed an interest in art and chose to study architecture. He attended the Czech Technical University in Prague from 1928 to 1932. During this time, he worked as a building engineer in Odesa. He married Cyla Müller in 1936.
World War II brought extreme danger to Wiesenthal and his family. When Germany invaded Poland in 1939, the city of Lwów was annexed by the Soviet Union. Later, the German invasion in 1941 changed everything for the Jewish population. The Nazis established the Lwów Ghetto, a restricted area where Jewish residents were forced to live. Wiesenthal and his wife were sent to the Janowska concentration camp in late 1941. There, he worked at the Eastern Railway Repair Works. He survived a long series of hardships, including the Kraków-Płaszów concentration camp, Gross-Rosen, and a death march to Chemnitz. Finally, he reached the Mauthausen concentration camp in early 1945.
The human cost of the war for Wiesenthal was immense. During the Holocaust, 89 of his relatives were murdered. This included his mother, who was killed at the Belzec extermination camp in August 1942. His wife, Cyla, also suffered greatly and her health was permanently damaged by her time in labor camps. Despite these losses, Wiesenthal survived the war. By May 1945, he was among the prisoners liberated by Allied forces.
After the war, Wiesenthal turned his focus to documentation and justice. In 1947, he co-founded the Jewish Historical Documentation Centre in Linz, Austria. This center helped gather information for future war crime trials. It also assisted Jewish refugees in searching for lost family members. In 1961, he opened the Documentation Centre of the Association of Jewish Victims of the Nazi Regime in Vienna. He worked to build dossiers, which are detailed collections of documents about a person or subject. These files were essential for proving the identities and actions of fugitive Nazi officials.
Wiesenthal's work involved several high-profile investigations. He played a small role in the 1960 capture of Adolf Eichmann, a Nazi official, by the Mossad in Buenos Aires. 
Even with controversies regarding his role in certain events or his memoirs, his impact was lasting. He was known to sometimes exaggerate his role in historical events in his writing. Despite this, his dedication to finding the truth remained central to his identity. He died in his sleep in Vienna in 2005 at the age of 96. He was buried in the city of Herzliya in Israel. His legacy continues through the Simon Wiesenthal Center in Los Angeles, which carries on his mission of fighting antisemitism and injustice.
