1802 HAYYIM VOLOZHINER (Belorus, Russia)
Founded the Volozhin Yeshiva. Rav Hayyim introduced in his school the hevruta style of study whereby one learns with a colleague rather then by oneself. Volozhin soon gained a reputation as one of the greatest Jewish centers of learning in the world. With its strict entrance exams and insistance on a high level of consistency, the school soon became the model for other schools of its kind, e.g. Mir (1815), Radun (1869), Telz (1875) and Navaredok (1896).
