Yeshayahu Leibowitz (Hebrew: ישעיהו ליבוביץ‎; 29 January 1903 – 18 August 1994) was an Israeli Orthodox Jewish public intellectual and polymath. He was a professor of biochemistry, organic chemistry, and neurophysiology at the Hebrew University of Jerusalem, as well as a prolific writer on Jewish thought and western philosophy. He was known for his outspoken views on ethics, religion, and politics. Leibowitz cautioned that the state of Israel and Zionism had become more sacred than Jewish humanist values and went on to describe Israeli conduct in the occupied Palestinian territories as "Judeo-Nazi" in nature while warning of the dehumanizing effect of the occupation on the victims and the oppressors.^[1]
