Rabbi Yaakov Lorberbaum of Lissa רבי יעקב לורברבוים מליסא
Netivot HaMishpat — the constant interlocutor and opponent of the Ketzot HaChoshen
Rabbi Yaakov Lorberbaum was born about 1760 and died in 1832; he is known by the town of Lissa, where he was rabbi.
Chavat Da'at on Yoreh De'ah he issued at Lvov in 1799 without the author's name. His chief book is Netivot HaMishpat on Choshen Mishpat, published in 1809–1816. It is written in constant argument with the Ketzot HaChoshen: most often Lorberbaum objects where Heller departs from the Tosafot. Heller answered with Meshovev Netivot, arguing that his reading was in fact the hidden logic of the Tosafot — and Lorberbaum answered again.
Today the Ketzot and the Netivot are printed on the same spread and learned together: the argument proved more fruitful than either opinion alone. That, incidentally, is a good answer to the question of what polemic is for in halakhah.
His Derech HaChaim, a short code of the laws of prayer, was printed in prayer books and generations prayed by it.
