Jacob Emden
Jacob Emden, also known as the Yaʿavetz (June 4, 1697 – April 19, 1776), was a leading German rabbi and talmudist who championed traditional Judaism in the face of the growing influence of the Sabbatean movement. He was widely acclaimed for his extensive knowledge.
Emden was the son of the hakham Tzvi Ashkenazi and a descendant of Elijah Ba'al Shem of Chełm. He spent most of his life in Altona (now part of Hamburg, Germany). His son, Meshullam Solomon, served as rabbi of the Hambro Synagogue in London and claimed authority as Chief Rabbi of the United Kingdom from 1765 to 1780.
The acronym Yaʿavetz (יעב״ץ, also rendered Yaavetz) is formed from his Hebrew name, Yaʿkov ben Tzvi (יעקב בן צבי).
Seven of his 31 works were published posthumously.
Jacob Emden (born Ashkenazi) was the fifth of his father's 15 children. Until the age of seventeen, he studied Talmud under his father, Tzvi Ashkenazi, a foremost rabbinic authority, first in Altona and later in Amsterdam (1710–1714). In 1715, he married Rachel, daughter of Mordecai ben Naphtali Cohen, rabbi of Ungarisch-Brod in Moravia (now Uherský Brod in the Czech Republic) and continued his studies in his father-in-law's yeshiva.
Emden mastered all branches of Talmudic literature and later expanded his studies to philosophy, kabbalah, and grammar—even attempting to learn Latin and Dutch despite his view that secular studies should be limited to periods when Torah study was not feasible.
Emden initially spent three years in Ungarisch-Brod as a private Talmudic lecturer before taking up work as a dealer in jewelry and other goods—a trade that required extensive travel. Although he generally declined formal rabbinic positions, in 1728 he accepted the rabbinate of Emden, from which he later derived his name. He eventually returned to Altona, where he secured permission from the Jewish community to establish a private synagogue. Early on, he enjoyed cordial relations with Moses Hagiz, head of the Portuguese Jewish community in Altona, though these later deteriorated due to calumnies. Similarly, his initially positive relations with the chief rabbi of the German community, Ezekiel Katzenellenbogen, later soured.
A few years later, Emden obtained permission from the King of Denmark to establish a printing press in Altona. He soon encountered controversy over his publication of a siddur he wrote in 1747 with commentary according to the minhag Polin, ʿAmmude Shamayim (עמדי שמים), harshly criticizing influential local moneychangers. Despite receiving the approbation of the Landesrabbiner, his opponents continued to denounce him.
