Personal details
Born	c. 1176 probably Mainz, Electorate of Mainz
Died	1238 Worms, Holy Roman Empire

Eleazar of Worms (אלעזר מוורמייזא) (c. 1176–1238), or Eleazar ben Judah ben Kalonymus, also sometimes known today as Eleazar Rokeach ("Eleazar the Perfumer" אלעזר רקח) from the title of his Book of the Perfumer (Sefer ha rokeah ספר הרקח)—where the numerical value of "Perfumer" (in Hebrew) is equal to Eleazar, was a leading Talmudist and Kabbalist, and the last major member of the Hasidei Ashkenaz, a group of German Jewish pietists.

Eleazar was most likely born in Mainz. He was a descendant of the great Kalonymus family of Mainz, and a disciple of Judah ben Samuel of Regensburg (Judah he-Hasid), who initiated him into the study of the Kabbalah, at that time little known in Germany. According to Zunz, Eleazar was hazzan at Erfurt before he became rabbi at Worms. In 1233 he took part in the Synod of Mainz which enacted the body of regulations known as "Takkanot Shum" (ShUM = "Speyer, Worms, Mainz"), of which he was a signatory.

According to the Jewish Encyclopedia, Eleazar underwent great sufferings during the Crusades. The Jewish Encyclopedia states that on the night of 22 Kislev, 1196, he was engaged on his commentary on Genesis (Eleazar relates that he had reached the parshah Vayeshev), when two Crusaders entered his house and killed his wife Dulcina, his two daughters Belat and Hannah, and his son Jacob. His wife had conducted a business in parchment scrolls in order to support the family and enable him to devote all his time to study. Many of the piyyutim he authored protest at Israel's suffering and hope for redemption and revenge against her tormentors. He also recorded the deaths of his family in a moving and poetic eulogy.
