[1] He was born in Vienna, the city to which his father had escaped during World War I together with his great-uncle, Rabbi Avrohom Yaakov Friedman, the third Sadigura Rebbe.

[3] In the spring of 1939, his father traveled to Palestine to visit his Ruzhin relatives and was advised by his uncle, Rabbi Yisrael Friedman, the Husiatyner Rebbe, who had emigrated there several years earlier, to remain.

[2] In 1965, when his father returned to Israel to open a court in Tel Aviv, Friedman stayed on as Rav of the Brooklyn beis medrash.

[1] He was the most right-wing member of the Moetzes Gedolei HaTorah,[7][8] expressing his strong opposition to the Oslo Accords and Israel's unilateral disengagement plan[2][9] and visiting Israeli settlements in the West Bank to bolster the Jews living there.

[4] At the end of December 2012 he came down with severe pneumonia, and was rushed to Ma'ayanei Hayeshuah Hospital in Bnei Brak on the morning of January 1, 2013 (19 Tevet 5773), where he died.

[4][5] His funeral, which set out from the Sadigura beis medrash in Bnei Brak in the early afternoon, was attended by the Rebbes of Boyan, Bohush, Kapishnitz, Vasloi, Ger, Vizhnitz, Toldos Abraham Yitzchak, and Sanz, as well as Litvishe gedolim.

[4] In keeping with tradition, no eulogies were said at this funeral of a Rebbe,[5] but his will was read, naming his only son, Rabbi Yisrael Moshe Friedman, av beis din of the Sadigura rabbinical court in London,[10] as his successor.
