Baalei HaNefesh, Berlin 1762 - Signature of Rabbi Meir Posner, Author of Beit Meir, and Glosses in his Hand

Baal HaNefesh, Hilchot Nidah by the Raavad, with Hilchot Nidah by the Ramban, and Chiddushei HaRan on Tractate Nidah. Berlin, [1762].
The (original) pastedown of the binding bears a handwritten signature of R. Meir Posner, author of Beit Meir: "Meir Posner Rabbi of Schottland". The book includes scholarly glosses in his handwriting (seven long glosses and several short revisions). Most glosses refer to the teachings in Chiddushei HaRan. The glosses were written in the characteristic style of the Beit Meir glosses and pose inquiries on the words of the Ran. These glosses are not known and have never been printed.
R. Meir Posner (1729-1807, Otzar HaRabbanim 12928) was a prominent rabbi and posek. He was named Posner after the time he lived by his father-in-law in Poznań after his marriage. After his wife died, he moved to Leszno where he studied with his companion R. David Tevil. In 1763, he served as Rabbi of Międzyrzec (Mezritch) and his fame spread throughout Poland. R. Akiva Eger exchanged extensive correspondence with R. Meir and considered him the supreme Torah authority of his days. In a responsum, R. Akiva Eger refers to R. Meir as "the truly outstanding Gaon… bright light" (dozens of the responsa in the Rabbi Akiva Eger responsa and in the book Beit Meir responsa originate from this correspondence). The book Beit Meir contains correspondence with leading Torah scholars of his times who wrote him their queries and deliberations. These include R. Yosef son-in-law of the Noda B'Yehuda, R. Yaakov of Leszno (Lissa), R. Shlomo Zalman, author of Chemdat Shlomo, R. Avraham Danzig author of Chayei Adam, etc. As of 1767, he served as Rabbi of Königsberg and later as Chief Rabbi of the Danzig union of communities [Schottland, Weinberg, and Langfuhr] for 25 years. He authored many books including his important work Beit Meir on the laws of Shulchan Aruch Even HaEzer.
