Editing Eliyahu Yeichil-Simpson (section)

== Life History ==
Born on Rosh Chodesh Tammuz 5649 to his father Rabbi Shimon Aharon and his mother Mrs. Henka in Bobruisk, White Russia.

At only age 12 in 5661, he entered to study at Yeshivas Tomchei Tmimim Lubavitch, and studied there and in its various branches for fifteen years, making him one of the tmimim who studied for the longest period in Tomchei Tmimim Lubavitch.

During his time at Tomchei Tmimim, he was considered an "[[Avodas Hatfilah|oved]]" who would spend long times in prayer, a practice he continued throughout his life. In later years, prominent Tomchei Tmimim graduates Rabbi Shlomo Zalman Havlin, head of Yeshivas Toras Emes, and the mashpia Rabbi Alter Simchovitz wrote letters recalling Rabbi Simpson's devotion to prayer.

During his years in Tomchei Tmimim, he invested all his powers and brilliant talents in studying nigleh and chassidus. After several years of deep study in Gemara and halacha, he received rabbinical ordination from the Gaon Rabbi Dovid Tzvi Chen, Rabbi of Chernigov, and from his childhood friend the Gaon Rabbi Leib Sheinin, Rabbi of Dokshitz.
