Tosafist of the thirteenth century. He wrote tosafot to a great number of Talmudical treatises, and is quoted in the "Kol Bo" (No. 87, on Berakot), in the Tosafot Yeshanim (on Yoma 14a), in the tosafot of Asheri (to Yeb. 14a; Ket. 17a; Ḳid. 16b; Naz. 65b; Zeb. 37b), and in the "Shiṭṭah Meḳubbeẓet" of Bezaleel Ashkenazi (on B. Ḳ. 70b). Judah was also the author of ritual decisions which are found in "Haggahot Maimoniyyot" (Hilkot "Ma'akalot Asurot," ) and in the responsa of Meïr of Rothenburg (ed. Lemberg, No. 487, on Niddah). Biblical explanations by Judah are quoted in the tosafot to the Pentateuch (Neubauer, "Cat. Bodl. Hebr. MSS." No. 270).
