Yaakov Lorberbaum
rabbi
Jacob Lorberbaum or Jacob ben Jacob Moses of Lissa (1760-1832) , Hebrew: יעקב בן יעקב משה מליסא) was a rabbi and posek. He is most commonly known as the Ba'al HaChavas Da'as or the Ba'al HaNesivos for his most well-known works, or as the "Lissa Rav" for the city in which he was Chief Rabbi.
Biography
Lorberbaum was the great-grandson of Tzvi Ashkenazi. According to one tradition, his father, Yaakov Moshe, died before he was born. His relative, Joseph ben Meir Teomim, the rabbi of Bursztyn, brought him up. This accounts for the common name that both father and son share. Another tradition states that before he was born, his father fell ill, and dreamed that he would recover in the merit of the son that would be born to him. In the merit of his future son, the father took his name-to-be. Another legend is that at his naming ceremony, his father was preoccupied with his study and thought they asked for his name. He studied under Meshullam Egra.
