The Kovno Kollel also known as Kollel Perushim of Kovno or Kollel Knesses Beis Yitzchok, was a kollel located in Kaunas, Lithuania. It was founded in 1877 by Rabbi Yisrael Lipkin Salanter when he was 67.
Kovno Kollel's purpose was the furtherance of hora'ah (expertise in deciding matters of Jewish law) and musar - by supporting and guiding exceptional Torah scholars in their development as authorities. The project received the blessings, and eventually the name, of the Kovno Rav and posek hador (the generation's outstanding authority in Jewish law), Rabbi Yitzchak Elchanan Spektor, the rabbi of Kovno.
Until 1877, yeshivas only subsidized students until they got married (at an early age). When the Kollel was established, Rabbi Salanter was attacked by many, precisely for this point. He instituted the practice of paying a small salary to married students to continue their advanced Talmudical studies. He defended this innovation because he said that he was training leaders. His argument was that the need for well-trained communal leaders mandated this drastic action. The justification was that these individuals would eventually serve the community, and it was not that because they sat and learned that they should be supported.
By 1877-1878, ten scholars had begun their full-time studies, following a curriculum which included the study of musar literature. In 1879, Rabbi Spektor became its head. Rabbi Nosson Tzvi Finkel served as the mashgiach of the kollel. Rabbi Spektor's son, Rabbi Zvi Hirsh Rabinowitz accepted the administrative responsibilities and was one of the roshei kollel (heads of the kollel), while Rabbi Avrohom Shenker and Rabbi Finkel conducted the internal affairs. Under the latter's guidance, the book Eitz Pri was published, featuring essays by Rabbis Salanter and Spektor - including a foreword by the then lesser-known Rabbi Yisroel Meir HaKohen (the "Chafetz Chaim").
