About HaRav Yitzhak Klauber of Posen


. . .when the Maharshal quotes his grandfather, R. Yitzchok Klauber, noted are many of the places where the Maharshal cites his grandfather, throughout his many seforim (p. 3, n.6), along with a brief biographical sketch. [5] The same style note can be found when the Maharshal mentions his father-in-law R. Kalonymus (Kalman) Havarkstein-Yerushalmi; a listing of other citations, along with a thumbnail bio, including the Maharshal's wife's name (p. 38, n.28).


Hebrew Books


Moses ben Isaac ha-Levi Minz (15th century) was a German rabbi and contemporary of Israel Isserlein, whom he frequently consulted. He was successively rabbi at Mainz, Landau, Bamberg, and Posen.

In his responsa (No. 114) he mentions a certain Jacob Margolioth of לוקו (Lucca?), and refers to a case of divorce in Posen in 1444 (Steinschneider gives 1474). Fränkel (Zeitschrift, iii. 387) doubts that Moses ever was at Posen. He suggests that פוזנו (Posen) is a printer's mistake for פיזרו (Pesaro).

Moses' responsa (Cracow, 1617) mention also Joseph Colon, Israel Isserlein, and his cousin Judah Minz. Responsum No. 46 contains a dispute over a philological point with Eliezer Treves (comp. M. Wiener in Monatsschrift, xvi. 390).

Jacobi: p. 216, 18.1: "... was a member of the Klaus..." I wonder if there is any relationship between the word Klaus and the surnames Klauber and Klausner?
