Rabbi Aharon Shmuel Kaidanover was a seventeenth-century communal rabbi and posek who held positions in numerous communities across Poland, Lithuania, and Germany. He authored Birkas haZevach, a work of chiddushim on the Talmudic order of Kodashim which contains an autobiographical preface detailing his wanderings during the wars of the period. After a career that included rabbinic posts in Vilna, Nikolsburg, and Frankfurt am Main, he was appointed Av Beis Din of Kraków in his final years.
