Roshei Yeshivot / Torah Luminaries
Great intellects, profound thinkers, and master teachers who examplify the grandeur of the Torah in our century. Their very names inspire awe:
Rosh yeshiva ראש ישיבה; is the title given to the dean of a Talmudical academy (yeshiva). The rosh yeshiva is required to have a vast and penetrating knowledge of the Talmud and the ability to achieve a level of mastery of his material and an ability to analyse and present new perspectives, called chidushim, (novellae) verbally and often in print.
Yeshivas continue the scholarly traditions of the sages of the Mishnah and Talmud who often headed academies with hundreds of students. In the Talmudic academies in Babylonia the rosh yeshiva was referred to as the Reish Metivta in Aramaic and had the title of Gaon.
There are familial dynasties of rosh yeshivas, for example the Soloveitchik, Finkel, Feinstein, Kotler and Kook families, which head many yeshivas in the United States and Israel.
