Rabbi Benjamin Beinush Finkel (1911 – February 13, 1990), universally known as Rav Beinush Finkel, was the third Rosh Yeshiva (dean) of the Mir Yeshiva in Jerusalem. He inherited leadership of the institution from his legendary father, Rabbi Eliezer Yehuda Finkel ("Reb Leizer Yudel"), and grandfather, the Alter of Slabodka.

While his predecessor, Rav Chaim Shmuelevitz, was the public intellectual powerhouse of the yeshiva, Rav Beinush was its quiet, humble, and fiercely dedicated heartbeat, serving as the primary administrator and spiritual anchor for nearly a quarter of a century.

Early Life and the Mir Miracle

Rav Beinush was born in Mir, Belarus, into one of the most distinguished rabbinic families in Lithuania. He spent his youth fully immersed in the rigorous academic and ethical training of the pre-war European yeshiva world.

• The Holocaust Escape: Alongside his brother-in-law, Rav Chaim Shmuelevitz, Rav Beinush was an active part of the Mir Yeshiva’s miraculous escape from Nazi-occupied Europe. He traveled with the entire student body on the Trans-Siberian Railway across Russia to Japan, and eventually spent the war years under Japanese occupation in the ghetto of Shanghai, China.

• Rebuilding in Jerusalem: After the war, he immigrated to Mandatory Palestine to rejoin his father, who had already begun laying the groundwork for the Mir Yeshiva in Jerusalem. Rav Beinush married the daughter of Rabbi Shmuel Greiniman (the brother-in-law of the Chazon Ish, one of the greatest halachic authorities of the era), further connecting him to the highest tier of Torah leadership.

Leadership of the Mir Yeshiva

Following his father’s passing in 1965, Rav Beinush officially assumed the mantle of Rosh Yeshiva. Under his stewardship, the Jerusalem branch experienced an extraordinary era of expansion.

• The Quiet Force: Rav Beinush was notoriously low-profile. He eschewed the spotlight, rarely delivering the massive public lectures (shiurim klaliim) that his father and brother-in-law were famous for. Instead, he chose to focus on the daily, microscopic running of the institution, ensuring its financial stability and spiritual integrity.

• A Master Builder: He oversaw the construction of massive new buildings in the Meah Shearim and Beis Yisrael neighborhoods of Jerusalem to accommodate the thousands of students pouring in from the United States, Europe, and Israel. It was during his tenure that the Mir transitioned from a local Lithuanian remnant into the largest single yeshiva campus in the world.

Key Characteristics and Legacy

1. Hidden Greatness (Nistar)

Rav Beinush was the epitome of a Nistar—a hidden righteous man. He went to extreme lengths to conceal his staggering knowledge of the Talmud and halacha. He spoke softly, dressed simply, and walked the halls of the yeshiva not as a ruler, but as a humble civil servant. Many young students who interacted with him daily to receive their monthly stipends had no idea they were speaking to a Torah giant of the generation.

2. Deep Sensitivity to Students

He possessed an innate, fatherly sensitivity for his students, particularly those who were far from home.

• He memorized the names and personal situations of thousands of bachurim (young men).

• He frequently paid tuition, health bills, and wedding costs for poor students out of his own pocket, strictly conditioning the help on complete secrecy so as not to embarrass them.

3. Passing the Torch to a New Era

Aware of his failing health in the late 1980s, Rav Beinush made a monumental decision for the future of the yeshiva. Breaking with traditional expectations, he chose his son-in-law, Rabbi Nosson Tzvi Finkel (an American-born scholar from Chicago), to succeed him as Rosh Yeshiva.

This decision was brilliant; Rav Nosson Tzvi possessed the exact same boundless love for the students and administrative vision, ultimately expanding the Mir into an empire of over 9,000 students.

Passing

Rav Beinush Finkel passed away on the 18th of Shevat (February 13, 1990) at the age of 79. His funeral in Jerusalem was stripped of the usual lengthy eulogies—at his own strict deathbed request—reflecting the absolute humility that defined his entire life. He was buried on Har HaMenuchot, leaving behind a monumental legacy of quiet devotion that ensured the eternal flame of the Mir Yeshiva would never be extinguished.
