Rav Yosef Shmuel of Cracow zt"l
Rav Yosef Shmuel of Cracow is the mechaber of Mesores HaShas. The Chida, in his biography of Rav Yosef Shmuel, wrote that he learned all of Shas forty-two times, fulfilling the mitzva of Vedibarta ‘bom’, (the numerical value of bom being forty-two). He also added that for twenty-five years he learned standing on his feet and all his learning was Torah lishmah (for the sake of Heaven).
