Reb Levi Yitzchak parents were Grand Rabbi Pinchos Dovid Horowitz and Rebbitzen Sora Sosha Horowitz. His father, founder of the Boston Hasidic dynasty, died in November 1941. In 1942, shortly after his father's death, he married Rachel Unger Leifer of Cleveland, Ohio, a descendant of Reb Naftoli Ropshitzer.
In 1943, Rabbi Levi Yitzchok Horowitz was one of the four hundred-plus rabbis led by Rabbi Baruch Korff who traveled to Washington, D.C. just before Yom Kippur, to plead with President Franklin D. Roosevelt to rescue Jews from Hitler.
In 1944, upon becoming the first American-born chasidic rebbe, he announced that his primary thrust as rebbe would be aimed at the area's large number of college students, many of whom were away from home and in a perfect position to partake of all that he felt the New England Chassidic Center could offer them. Many tried to dissuade him, saying that chasidus and college did not and could not mix, but the Rebbe persevered and was personally responsible for returning many hundreds of students at Harvard University and Massachusetts Institute of Technology to their Jewish roots.
In 1984, the Rebbe made a decision to create a Chassidic community in Har Nof, Jerusalem, Israel. In 1999, an additional community was established in Beitar, for the next generation of Bostoner Chassidim.
The Rebbe suffered a cardiac arrest on July 6, 2009, and hospitalized in the Sharei Tzedek hospital in Jerusalem. He died at the Sharei Tzedek Medical Center, on Saturday, December 5, 2009 (Shabbat Vayishlach). He was buried the same night on the Mount of Olives..
