(MaHaRSH”A). Chidushim Mi’Masecheth Nidah [Halachic and aggadic novellae and on Tractates Nidah and portion of Nedarim]

A native of Cracow, R. Samuel Edels (1555-1631) is unusually referred to by his mother-in-law's name. A wealthy woman, she supported the scholar and his disciples for a period of twenty years (1585-1605). In 1625, Edels established an important yeshivah in Ostrog. See EJ, Vol. VI, cols. 363-4 The Maharsh”a’s supercommentary 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)
