Rabbi Meir Brandsdorfer (Hebrew: מאיר ברנדסדורפר; 7 September 1934 – 13 May 2009) was a member of the Rabbinical Court of the Edah HaChareidis, the Haredi Ashkenazi community in Jerusalem, and was in charge of their Kashrut operations, especially matters of Shechita.
He was a proclaimed mohel. His responsa have been published under the title Knei Bosem.
He was born on 7 September 1934, in Antwerp, Belgium to his parents, Shlomo and Frumit. After surviving World War II while hiding out in France, he moved to Palestine together with his family.
He became the rabbinical leader of the Toldos Aharon Hasidic movement, based in the Jerusalem neighborhood of Meah Shearim. When Toldos Aharon's previous rebbe died, he joined the split-off group named Toldos Avraham Yitzchok. He was highly respected and eulogized by both groups upon his death.
The position of rabbinical leader in a Hasidic dynasty is not identical to that of rebbe: the rebbe is the spiritual leader, while the rabbinical leader - rabbi - is the halachic expert, who leads the group in questions of Jewish law. While in some Hasidic groups the rebbe also fulfills the position of rabbinical leader, in other groups this position is separate.
