As the eldest son of Moshe, Horowitz succeeded his father as the Bostoner Rebbe of New York.[5] He later founded the Bostoner community in Ramat Beit Shemesh, Israel, where he resided.[6] He composed contemporary Chasidic music;[7] many of his compositions were performed by leading Jewish music artists of the day.[8]Andy Statman[9] credits him with being a major influence in his musical career, having performed several of the Horowitz's compositions on his recordings and in concert.
In 1954, Horowitz married Miriam Adler, daughter of Rebbe Elazar Adler of the Zvhil dynasty, who gave birth to their son Yaakov Yitzchak "Yankel" in 1956.[citation needed] He was raised in his maternal grandparent's[clarification needed] home in the West Hollywood section of Los Angeles, and now serves as rabbi of the Bostoner Shul in Lawrence, New York. Horowitz married the daughter of Yonah Hass in his second marriage. They have one son, Yisrael Yona, and seven daughters.[citation needed]
