Gershon Chanokh Leiner of Radzin
Also known as The Radziner Rebbe
1839 CE–1891 CE · Hasidic · Radzin (Radzyń Podlaski)
Gershon Chanokh Leiner of Radzin (c. 1839–1891) was a Hasidic master and the founding rebbe of the Radzin dynasty in Radzyń Podlaski, Poland. He was known for his profound mystical scholarship and his passionate commitment to recovering and restoring the use of tekhelet (blue dye) for tzitzit, which had been lost to Jewish practice for centuries. Drawing on Talmudic sources and extensive research, he conducted experiments to identify the authentic source of tekhelet and advocated for its reintroduction in observant communities—a legacy that continues to influence Jewish practice today. He was revered by his followers for his piety, learning, and innovative approach to halakhic and Kabbalistic questions, combining rigorous textual study with mystical insight.

Radzin (Radzyń Podlaski) in this era
Under Russian imperial rule following the Congress of Poland's absorption into the Russian Empire, Radzin was a small but vibrant Jewish town in the Lublin region, with the Radziner Rebbe at its spiritual heart. The Jewish community, numbering in the hundreds, looked to him as a revered Hasidic leader and kabbalist whose teachings on wool-dyeing for ritual tzitzit fringes reflected his unique blend of practical innovation and mystical devotion. During these final decades of the nineteenth century, even as Russian-Jewish life faced increasing restrictions and conscription pressures under the Romanovs, Radzin remained a center of Hasidic learning where the Rebbe's court attracted followers seeking his guidance in Torah and Kabbalah. The Radziner's own deep scholarship and his distinctive approach to Jewish law and practice—including his controversial revival of the use of blue dye (tekhelet) in ritual fringes—made his small town a destination for serious students despite the empire's tightening grip on Jewish autonomy in Poland.
