, Rabbi Unterman worked on behalf of Jewish refugees from Germany who were treated as enemy subjects by England. He risked himself by visiting them in detention and visiting members of his community who were dispersed to find shelter.
After the passing of Rabbi Moshe Avigdor Amiel in 1945, Rabbi Unterman was appointed as the Ashkenazi rabbi of
Tel Aviv

. He refused to immigrate to
Eretz Yisrael using the general immigration quota and instead received a special immigration permit from the British as a "British expert in the rabbinate."
In Tel Aviv, Rabbi Unterman established a kolel named "Shevet Meyehuda" and wrote halachic responses and various articles, compiling his main responses in his work: ''Shevet M'Yehuda''. Together with the Sephardi rabbi of the city,
Yaakov Moshe Toledano, he founded the special court for
agunot issues.
Rabbi Unterman also served as a
dayan in the Great Rabbinical Court. In 1955, he was elected to the
Chief Rabbinate Council, and on

3, 5724 – March 16, 1964, he was elected as the
Ashkenazi Chief Rabbi of Israel, defeating Rabbi Goren by three votes. Rabbi Unterman served in this position until 1972, when he lost the election to Rabbi
Shlomo Goren, an outcome he interpreted as a dismissal.
Rabbi Unterman passed away in 1976 and was buried on the
Mount of Olives in Jerusalem. Streets in Tel Aviv, Jerusalem, Petah Tikva, and Netanya are named after him.
He was married to Rachel Leah (née Yellin), and they had seven children. One of his sons, Baruch, served as a director at
Bar-Ilan University. One of his granddaughters,
Reva Mann, recalls his tolerance, saying that even though she did not observe Torah and mitzvot, her grandfather "loved her unconditionally."
Halachic rulings and approach
Rabbi Unterman was a classic
Litvak scholar deeply influenced by the unique halachic approach of his teacher, Rabbi
Shimon Shkop, as reflected in his classes and halachic responses—discussions based on logical reasoning and the use of logical tools typical of his mentor. On the other hand, unlike Rabbi Shkop, Rabbi Unterman also addressed contemporary halachic issues of his time (many of which remain relevant today), such as:
ascending the Temple Mount,
conversion, marriage prohibitions,
mitzvot dependent on the land, drafting women to the
IDF, and many others.
Compared to other Orthodox rabbis of his time, Rabbi Unterman was considered a liberal
posek. For example:
* When a woman offered her hand in greeting, Rabbi Unterman shook her hand, saying, "I am not lenient about touching, but I am strict about human dignity."
* Another example is his lenient approach toward accepting converts from the immigrants of the Soviet Union, about whom he wrote:
Regarding new halachic issues concerning technological and scientific aspects, his approach tended to be lenient, for example, on
organ donation. Initially, Rabbi Unterman (like most rabbis of his time) believed it was forbidden, but after it was proven that death could be determined scientifically and accurately, he permitted organ transplants and even introduced an argument to allow benefiting from a dead body, which remains used by contemporary halachic authorities. He also wrote in response to Rabbi Ketheriel Fishel Tikhuresh's article about the question posed by
Bar-Ilan University on using
embryonic stem cells:
Rabbi Unterman supported the recitation of
Hallel on
Yom Ha'atzmaut, but since we do not have the authority that the sages had to establish new blessings, he hesitated about whether to recite the blessing before Hallel, invoking the name of God. On the other hand, on
Jerusalem Day, Rabbi Unterman argued that Hallel should be recited with a blessing, as it is a celebration of a transition from death to life.
[Rabbi Yehuda Amital]
The Day of Hafatzeiva
- Jerusalem Day Talk, 5757. Nevertheless, he asserted that Yom Ha'atzmaut takes precedence over Jerusalem Day because Yom Ha'atzmaut symbolizes human revival, while Jerusalem Day is a miracle of divine providence.
