Jack A. Kessler (1944–2024) was an American hazzan, musician, and educator. After working as a cantor for synagogues for 20 years, he organized several musical ensembles including Atzilut, a group of Jewish and Arab musicians, which toured venues around the world including the United Nations.[1] He also adopted the practice of chanting trop for haftarah and other biblical texts in both Hebrew and English to make the text more vivid and alive for synagogue worshippers.[2]
