The project began at the initiative of Rabbi
Meir Bar-Ilan (Berlin) (1880–1949), the son of the
Netziv. The concept was first described in a 1921 lecture by
Chief Rabbi Abraham Isaac Kook, who outlined several projects for Torah scholars, including a work "that elucidates the essence of Torah principles, organized by encyclopedic entries." Bar-Ilan organized a group of notable editors. The purpose was to summarize all the Talmudic discussions and all the opinions of
Rishonim and
Acharonim in encyclopedia articles in alphabetical order. The first edition of the first volume was published in 1947. This volume included 219 articles in an organized format of summaries. The same volume was reprinted three more times: in 1947, 1951, and 1955. After Bar-Ilan died in 1949, it was republished in a newly revised and expanded edition. In 1947
Encyclopedia Talmudit won the city prize of
Tel Aviv for Torah literature to honor the memory of Rabbi
Abraham Isaac Kook. Major Torah scholars, both
Hasidim and
Mitnagdim, supported the project. Supporters included Rabbi
Menachem Mendel Schneerson, Rabbi
Moshe Feinstein, Rabbi
Yosef Shalom Eliashiv, Rabbi
Yochanan Sofer, and others. The administrator of the encyclopedia from its founding was Rabbi
Yehoshua Hutner (1910–2009), who succeeded in securing the initiative with stable financial backing, thanks to his connections with leaders of the
Mizrachi movement. ==Editors==
