Rabbi Yaakov Yisrael Kanievsky, the Steipler (1899-1985), was born in Hornostaipil (Steipel), Ukraine, hence his name. His father, a Chernobyl Chassid, died when he was seven, and he grew up in poverty.

Recruited by the Novardok yeshiva, he became one of its finest students. Forcibly drafted into the Red Army, he continued to observe the mitzvot scrupulously. The Chazon Ish, impressed by his writings, gave him his sister in marriage and brought him to Bnei Brak.

His major work, Kehillot Yaakov, is a profound analysis of the Talmud. He was also consulted by thousands for advice and blessings. His son, Rav Chaim Kanievsky, became one of the leaders of the Torah world.
