Erich Wasicky (May 27, 1911, in Vienna – May 28, 1947, at Landsberg Prison, Landsberg am Lech, Allied-occupied Germany) was a pharmacist at the Mauthausen concentration camp in charge of gassing victims.
The exact number of his victims is not known, but more than 3,100 died in neighboring Hartheim concentration camp, which fell under Wasicky's jurisdiction.
After the Nazis started using the poison Zyklon B, Wasicky was put in charge of establishing this process in both Mauthausen and Hartheim.
According to witnesses, Wasicky worked closely with SS doctor Aribert Heim.
The two performed gruesome experiments together, such as injecting various solutions into the hearts of Jewish prisoners to see which killed them the fastest.
