Dinah Horovitz was born on March 17, 1953 in Washington, DC to Emmanuel and Bernice Wolf. She grew up in Silver Spring, MD in a non-religious home, but studied in a Jewish school.
In 1971, at the age of 18, Dinah came to Israel to study at the Michlalah. She stayed at the home of Leah and Moshe Horovitz, who she knew from having studied in the school which was headed by Rabbi Moshe in the US. There she met her husband Elli. The two were married in 1973 and had 4 children. In 1986 they moved to Kiryat Arba where both taught at a variety of religious schools.
Rabbi Elnatan (Elli) and Rebetzin Debbie (Dinah) Horovitz were slain on Friday evening, March 7, 2003 as two terrorists, disguised as yeshivah students, infiltrated Kiryat Arba and shot the couple as they sat at their Shabbat table. Survivors include four children, Rav Elli's parents and Debbie's mother. The rabbi was a popular teacher and the couple was beloved by their community.
