For close to a century, Rav Yosef Shalom Elyashiv (April 10, 1910 - July 18, 2012) was a fixture in the Meah Shearim neighborhood of Yerushalayim, studying Torah day and night. At the time of his passing, he was the world-recognized authority on Jewish law and acknowledged leader of the non-Chasidic Torah community.
His life revolved around his diligent Torah study. His sweet singsong voice rang out at first in the Ohel Sarah shul, and then resonated to every corner of the Torah world, through the thousands upon thousands of piskei halachah he issued and the profound guidance - in matters public and private - that he offered.
