Yerahmiel was born in Jerusalem, in 1945, immediately after the Holocaust, to his parents Yaacov Liber and Chava.
When he was 3 years old, his father was killed in the War of Independence by shrapnel hitting the truck he was driving. 3 years later, his mother remarried to Menachem Goldstein, a widower and Holocaust survivor who had lost his wife and 3 children in the Holocaust. From then on his name would be Yerahmiel Goldstein, until his marriage.
Yerhamiel’s parents lived in the Agudat Yisrael housing in Sanhedria and Bayit Vagan neighborhoods of Jerusalem, and he himself went to Shiloh school, and at the age of 13 won the national competition for knowledge of Talmud in his age group.
Yerahmiel went to Yeshivat Kol HaTorah of Ponevich and at Grudna in Ashdod, where in 1968 he married Nili Schwartz from Bnei Brak. They settled in Ashdod and lived there until 1987, when they moved to the Jerusalem neighborhood of Har Nof.
In his years of study at Grudna, as a young scholar and after marriage, he started organizing all sorts of social activities for the less fortunate, including helping children get into the education system, visiting the sick, organization of summer camps and Yeshiva learning for the uneducated, opening of Kolels in the area, and management of the offices of Yad Sarah and Yad La’Achim in Ashdod.
At the same time, his rabbi Rav Karlinstein zt”l, appointed him to voluntarily manage a girls elementary school in Ashdod, which he did to his last day.
In addition to the above, he also held Torah positions in the Yeshiva and Kolel of Ateret Zvi, and in 1980 was appointed to Rosh Yeshiva of Hazon Yehezkel, where he held the position until 1988.
Upon his arrival in Har Nof, he opened an evening Kolel for people less educated in Torah, in addition to a Friday Kolel and a summer camp project for young Yeshiva students which was held 3 times a year for 17 years. In Har Nof as well, he did many things for the community, including being head of the “modesty and Shabbat watch”. Many important undertakings carried out at the beginning of Har Nof’s journey as a new neighborhood were attributed to him.
In 1990 he went to be a supervisor in the “Ta Shma” organization, an organization that supervises independent education institutions. He served there for 7 years, and afterwards initiated Project Toronto at the blessing of R’ Aharon Tzvi Gestatner, R’ David Hofstatter and R’ Motti Kroyzer. After 5 years of activity, this project turned into “Achinu”, which merged with the “Darshu” organization where he served as supervisor of the pre-prayers Torah learning.
In 1998, he was appointed principal of a girls high school in Ashdod, named “Beis Yaakov Forefathers”, a position he holds to this day.
Additionally, in the past 30 years he has travelled to the USA and Mexico for the “Helping Children Fund” which he founded with R’ Hayim Fuks.
From a young age and to this day, he continues to lecture on a variety of subjects to a wide span of age groups, all over the world and on radio stations. He also wrote many articles over the years in the Yated Neeman and other newslets such as “Or Hahar”, “Around the table” and more.
Within a short period of time, these articles turned into a series of books that grace the bookshelves of Jewish homes.
