Elsie Naomi Davis Schryver (1876-1933), born in Derby, England, was a Jewish translator of liturgy and a mother. She was born at Friarfield House, Derby, the oldest of two children of Louisa (née Jonas) and Arthur Davis. Her father's family were secular Jewish precision instrument makers, who had immigrated to England from Bavaria in the early nineteenth century. A civil engineer by trade, Arthur Davis became religiously observant and mastered the Hebrew language, becoming an accomplished Hebraist noted for his study of cantillation marks in the Tanakh. The family moved to Kilburn, London when Nina was six weeks old, later settling in Bayswater. There, Davis gave his daughters an intensive scholarly education in Hebrew and Jewish studies, teaching them himself each morning before breakfast from the age of four, and taking them regularly to the synagogue. The Davis's moved in learned Jewish circles, and friends of Nina's parents included the families of Nathan Adler, Simeon Singer, Claude Montefiore, Solomon Schechter, Herbert Bentwich, and Elkan Adler. Arthur Davis was one of the "Kilburn Wanderers"—a group of Anglo-Jewish intellectuals that formed around Solomon Schechter in the 1880s—members of which took an interest in Nina's work and helped her find publication for her writings. Eleven of Elsie's translations of piyyutim are credited in the maḥzorim of Herbert Adler and her father Arthur Davis. With her husband, Samuel Barnett Schryver, she was the parent of two daughters, Rosalind Leah Schryver and Priscilla Naomi Schryver. Elsie was the older sister of Nina Salaman Davis (1877-1925), who also translated medieval piyyutim.

Elazar ben Qallir, also known as Eleazar Kalir, Killir, Qalir or El'azar HaKalir (c. 570 – c. 640) was a Hebrew poet whose classical liturgical verses, known as piyut, have continued to be sung through the centuries during significant religious services, including those on Tisha b'Av and on the sabbath after a wedding. He was one of Judaism's earliest and most prolific of the paytanim, Hebrew liturgical poets. He wrote piyutim for all the main Jewish festivals, for special Sabbaths, for weekdays of festive character, and for the fasts. Many of his hymns have found their way into festive prayers of the Ashkenazi Jews' nusaḥ. (via wikipedia).
