(MaHaRHS”A). Chidushim MiMasecheth Yom Tov U’Masecheth Yevamoth ve’od [Novellae on Tractates Beizah and Yevamoth, etc.] Contains also novellae of R. Baruch of Mayence (author of Sepher HaTerumoth) to second chapter of Bava Bathra (on f.14v.)

The great supercommentator to Tosaphoth, Maharash”a (Moreinu Harav Shmuel Adels, 1555-1631) is unusually referred to by his mother-in-law Adel's name. A wealthy woman, she supported the scholar and his disciples for a period of twenty years (1585-1605). See EJ, Vol. VI, cols. 363-4. The Maharsh”a is indispensable to a proper understanding of Tosaphoth, the medieval French commentary to the Talmud. R. Abraham Isaiah Karelitz (author of Chazon Ish) was known to stress this as did R. Chaim Soloveitchik of Brisk (according to family oral testimony)
