[1][2] In 1888, at age 11, Dov Berish was sent to Olkusz to study the Torah for three years under the tutelage of Rabbi Lublinski.

After mastering and memorizing several tractates of gemara, he was tested by his father and then accepted into his yeshiva in Mstów, where he was considered one of the best students.

Upon assuming leadership of the yeshiva, he chose to rename it Nachlas Efraim, in memory of his father.

In 1942, during the holiday of Shavuot, Nazi soldiers ordered Einhorn to board a train to the Treblinka extermination camp.

[6][better source needed] In 1990, Einhorn's insights into the Torah were posthumously published together with those of his father, in a book called Shearis Efraim-Dov.
