The extermination of Jews had its own architect:Adolf Eichmann.During WWII he was responsible for the massacre of 6 million Jews, many in concentration camps. A brutal war criminal, Eichmann almost escaped being brought to justice.
Eichmann was born on March 19, 1906. in Solingen, Germany. He was an average student. Eichmann was fascinated by the Nazi party's rise to power in Germany. In 1932 he joined the Nazi party, soon becoming a member of a special group, the SS(Schutzsataffel.)He trained at Dachau, an infamous concentration camp. He was part of the SS which was concerned with the extermination of Jews, the Final Solution. He began terrorizing Jews by arranging for them to be publicly brutalized and humiliated. The dissolution of Jews' rights commenced.
Jews were forced to give up their belongings. 150,000 Jews were expelled from Austria. They were resettled in concentration camps where many were immediately executed. Jews died from a myriad of reasons: strenuous labor, disease, starvation, and exhaustion.
Systematically ridding Europe of its Jewish population became Eichmann's obsession. He did not involve himself in the actual genocide until January,1942.At the end of the war Eichmann was captured but managed to escape from Germany to Argentina. The Eichmanns lived in Buenos Aires until 1960 when Adolf was abducted by the Israeli Mossad.
Found guilty of crimes against humanity Eichmann was executed on May 31 in Tel Aviv.
