Yosef Yitzchak Jacobson

Jacobson lives with his family in Monsey. His siblings are author Simon Jacobson, Boruch Jacobson—a Chabad shliach at Hunter College, Freida Hecht of Norwalk, Connecticut and Chana Krasnianski of Manhattan.

Jacobson was initially tested on his semikhah (rabbinic ordination) by Pinhas Hirschprung as well as by Zalman Labkowsky. Having to still complete a last part of his test, Jacobson returned to 770 in 2011 to get tested and receive his rabbinical ordination through Labkowsky.

In 2005, Jacobson followed in the footsteps of his late father Gershon Jacobson as editor-in-chief of the Yiddish weekly Algemeiner Journal, which he contributed to for a number of years. He is a mashpia (spiritual mentor) at the Chovevei Torah Yeshiva in Crown Heights, Brooklyn, and a teacher at the Ohr Chaim Learning Center in Monsey, New York.

In 1988, at the age of 15, Yosef Yitzchak was recruited by his brother Simon to join the team that prepared the public addresses of Menachem Mendel Schneerson for publication. This role is known as a choizer or meiniach. Not being able to use recording devices because of Shabbat and Jewish Holidays observance, they were charged with memorizing talks, lasting many hours. After Shabbat or the Jewish Holidays he would get together with the rest of the team to transcribe those public addresses.

Yosef Yitzchak Jacobson (Hebrew: יוסף יצחק יעקבסון or ג'ייקובסון ‎) (born 1972), also known as YY Jacobson, is an American Chabad rabbi and speaker from Monsey, New York.

Yosef Yitzchak Jacobson was born on 11 June 1972 in Crown Heights, Brooklyn and grew up there as part of a Chabad Hasidic family. He started his studies in Oholei Torah, after which he moved to study in Chabad's Central Tomchei Temimim Yeshiva of 770 Eastern Parkway.
