Shlomo HaKohen (Vilna)
Rabbi Shlomo HaKohen (; 1828–1905) was the famed Av Beis Din (supreme justice of a rabbinical court) and Posek (decider of Jewish Law) of Vilna. In 1828, Shlomo was born to Rabbi Yisroel Moshe HaCohen, a dayan in the rabbinic court in Vilna. As a young child, Shlomo was known for his diligence and devotion to Torah study. When Shlomo was thirteen years old, he became deathly sick and his doctors told him that he must stop studying Torah because the intensity of his studies was adversely affecting his weak heart. Nonetheless, Shlomo refused to relent, and continued  to study Torah, as he reasoned that Torah is his life. HaKohen's glosses on the Talmud were published in the Vilna Edition Shas under the name "Cheshek Shlomo" (חשק שלמה). Rabbi Shlomo's halachik responsa were published under the title "Binyan Shlomo" (שו"ת בנין שלמה). HaKohen was a childhood friend of Rabbi Alexander Moshe Lapidus, also a native of Vilna. Rabbi Shlomo also corresponded with Rabbi Chaim Hezekiah Medini, who frequently praised and quoted from Rabbi Shlomo in his magnum opus, "Sdei Chemed". His responsa have gained a position of prominence in halachic literature, and are frequently quoted. Rabbi  Shlomo HaKohen was the editor of the Vilna Edition Shas, where he pored through various manuscripts to verify and establish an accurate version of the Talmud without the mistakes so prevalent in previous editions of the Talmud. As a critical scholar, Rabbi Shlomo HaKohen researched the text of Ketuvim based on various writings of the Vilna Gaon. Rabbi Shlomo HaCohen was allegedly an enthusiastic supporter of the Mizrachi Religious Zionism movement. However, claims that Rabbi Shlomo honored Theodor Herzl by greeting him with a Torah scroll in hand and described him as the equivalent of the Jewish kings of the  Biblical era are false. Rabbi Shlomo HaKohen was a great-grandfather of Rabbi Nochum Partzovitz.
