Grand Rabbi Yitzchak Glikman, Rebbe of Sosnowiec

Rabbi Icchak Glickman (nicknamed “Icekel”) was born in 1876 in the house of the Rabbi of Zolkiew, Rabbi Alter Rokeach, a relative of the Rabbi of Belz. As a child, he excelled in his studies and was ordained to be Rabbi at the age of 12. He was called the “Zolkiewer Prodigy”. He married the daughter of the Rabbi of Welbrum and continued his studies. After his death he was represented by his son, Rabbi Jehoszua.

(Note: per birth records in the Polish archives, accessible via JRI, he was born on June 3, 1875. Also note that records of him in his adult life refer to him as "Henoch Glikman", whose identity he assumed due to legal troubles as an Austro-Hungarian citizen in Congress Poland.)
