Uzzi Ornan

Since the 1990s he has been active in the "I am Israeli" movement, which strives for equality among all Israelis, by dropping the nationality from the formal government registration of each citizen or revising the nationality to include "Israeli" as an option. To this end, several appeals were submitted to Israeli courts.

In 1987 he was a visiting professor at the Technion - Israel Institute of Technology in Haifa. He managed a laboratory for natural language computing for its department of Computer Science. He continued to teach and head a laboratory at the Technion until his death. In the 1990s Ornan developed a new standard for the Latin presentation of Hebrew, that allows for complete reversibility between the Hebrew and the Latin script. The standard was adopted by the International Organization for Standardization as ISO 259-3.

In the internment camps he taught Hebrew phonology and morphology to other detainees. Following his return to Israel, he published his method as Diqduq ha-pe ve-ha-'ozen (Hebrew for "Grammar of Mouth and Ear"), which became a classic method for learning Hebrew grammar skills in high schools. He soon started studying at the Hebrew University of Jerusalem, where he received his Hebrew Linguistics PhD in 1964. He served his alma mater as lecturer and professor until 1987. In 1979 he was elected as a member of the Academy of the Hebrew Language. Ornan headed its committee that set the standards for Hebrew punctuation. In his research, he leaned toward a formal approach. Throughout the years he became increasingly interested in natural language computing.

In 1950 he founded the League Against Religious Coercion, in which he served as secretary and chairman until 1967. In the 1970s he was chairman of the Israeli Secular Movement. He was an opponent of circumcision. His remarks about religious coercion have led to complaints from Knesset members and human rights groups to incite violence. He said in an interview that "without a rebellion it is doubtful whether the religious coercion will change" to the reporter's question about the nature of the rebellion Arnon answered "one that even involves suspending people on an electricity pole". On another occasion Ornan said to a religious Knesset member Nissim Zeev during a talk show: "You should be thrown into the sea, and all your schools should be closed". Ornan corrected himself later he meant only to throw the schools to the sea, not the people, as one might understand.

In his youth, Ornan was active in the Irgun as a bomb-maker. In 1944 he was detained by the British authorities. Subsequently, he was deported to and imprisoned in British prison camps in Eritrea, Sudan and Kenya, where he was held until the Israeli Declaration of Independence in 1948.
