Mordechai Dovid Alpert

Mordechai Dovid Alpert (Hebrew: מרדכי דוד אלפרט; 1850 in Slonim – 1918 in Svislovich, near Bobruysk) was born into the family of Rabbi Chaim Shabtai Alpert known as "Chaim Matmid" and who was a great-great-grandson of Aryeh Leib Epstein (Ba'al ha-Pardes) of Königsberg.

He soon abandoned his rabbinic duties in order to concentrate on Talmud research and his writings.

His published works included sefers (books) Yad Morcechai,[1] Binyan Dovid,[2] Divrei Dodim[3] and Chemed Mordechai.

He left some unpublished manuscripts that now reside in Hebrew University in Jerusalem and The Rambam Library in Tel-Aviv.

Rabbi Alpert died during World War I while Germans occupied Svisloch.
