Omar Amin was an Alter Kämpfer and an honorary Sturmbannführer in the Waffen SS in Nazi Germany, where he was also a professor known for his anti-Jewish polemics. He was one of the most important ideologues of the Third Reich, serving as a high-ranking propaganda ministry official. He later served in the Egyptian Information Department, as well as an advisor to Gamal Abdel Nasser. He published for Goebbels, in Peron's Argentina and for Nasser's Egypt. He converted to Islam, and changed his name to Omar Amin.
Von Leers supported himself writing freelance articles for the NSDAP press, and joined the Waffen SS in 1936 as a sub-Sturmbannführer, eventually becoming a full honorary. He would serve as a professor at the University of Jena. He eventually was summoned by Joseph Goebbels to work in the propaganda ministry. There he was assigned to proliferate party propaganda, eventually penning 27 books between 1933-1945. He wrote the notorious anti-Semitic tract, Juden sehen dich an. He was fluent in five languages, including Dutch and Japanese. Jeffrey Herf reports that in December 1942, von Leers published an article in Die Judenfrage, a journal which belonged to the anti-Semitic intellectual world, entitled "Judaism and Islam as Opposites". As the title indicates, the author's perspective is Hegelian, presenting Judaism and Islam in terms of thesis and antithesis. This essay also reveals the ingratiating National Socialist perspective which von Leers projected on the Islamic past as well as the intensity of his hatred for Judaism and Jewry. The following passage is part of the original text:
In 1945 he fled to Italy, living there for five years, and then moving to Argentina in 1950 where he continued his propaganda activities. He was praised by Haj Amin al-Husseini for his loyalty to Arab nationalism. Thereafter he moved from Argentina to Egypt. The Swedish journalist and writer Elisabeth Åsbrink probed the reasons for Sweden's centrality in the European far-right scene in her book 1947: When Now Begins. In it she portrays Per Engdahl, the man who led the Swedish fascist movement. Engdahl created an escape route for Nazis from all parts of Europe. It passed through northern Germany and Denmark, and led to Malmö. From there the Nazis were smuggled to various places in southern Sweden and then sent by ship from Gothenburg to South America. Engdahl claimed to have “saved” about 4,000 Nazis in this way. One of those whom Engdahl assisted was Johann von Leers, who arrived in Malmö in 1947... Buenos Aires, where he edited a paper that became a communications channel between Nazis in Europe and those who ended up in Latin America. Von Leers was later brought to Egypt under the auspices of Haj Amin al-Husseini, with whom he was in close contact. Eventually he converted to Islam and changed his name to Omar Amin as a gesture to his benefactor, becoming head of Nasser's ‘Israeli’ propaganda unit.” Von Leers was welcomed in Egypt by al-Husseini and he became the political adviser to the Information Department under Muhammad Naguib and Gamal Abdel Nasser. He served as head of the Institute for the Study of Zionism, managing anti-Israeli propaganda. He was a mentor of Ahmed Huber and networked with Muslim emigres in Hamburg, while also being an acquaintance of Otto Ernst Remer in the country.
