In 1869, when the Chofetz Chaim returned from
Vasilishki to Radun, his first action was to establish a group to whom he could spread the knowledge of Torah. The founding of the yeshiva is mentioned in one of the letters of the Chofetz Chaim: :
"The beginning of the founding began from when I returned from the town of Vashilyshok...in the year 1869. Following my arrival in Raduń, the Almighty stirred my spirit to gather young students and scholars for the study of Torah..." Although at the time Raduń was practically an isolated village, away from undesirable urban distractions and an ideal location for establishing a place of Torah study, living conditions were difficult. This meant that the chances of garnering enough local financial support to run a large and prosperous institution were low. This led the Chofetz Chaim to send some boys to other yeshivas, which also had better facilities, and keep the enrollment limited. The students of the yeshivas made do with sleeping on the benches in the study hall and were referred to as "perushim" because they separated themselves from worldly luxuries and immersed themselves in study of Torah. From the start meals weren't provided at the yeshiva and students were allocated to various homes in the village where they were given meals. It was when the Chofetz Chaim felt that this set up was not befitting of yeshiva students that he abolished the so-called "
teg-essen" and went about arranging a house to house food collection. The collected food would then be distributed among the students. After some time a kitchen was opened by the wife of the Chofetz Chaim and she together with other women would collect provisions and cook meals which were served to the students in the yeshiva building. The yeshiva remained small in number until 1883 when the Chofetz Chaim took on his son-in-law Rabbi
Hersh Levinson as an assistant to help carry the burden running the yeshiva. After his appointment, the yeshiva expanded and the conditions improved. In 1900 Rabbi
Moshe Landynski, an alumnus of the
Volozhin Yeshiva, was appointed
rosh yeshiva. At later stages two other deans were in turn appointed: Rabbi
Yitzchak Maltzon, who eventually settled in
Jerusalem, and Rabbi
Baruch Ish Alaksot, who later became a rosh yeshiva in
Slabodka Yeshiva. Rabbi
Eliezer Lufet also served as
mashgiach ruchani for a short period.
New yeshiva building In 1904, after the influx of students, the local
Beth midrash became too small to accommodate the yeshiva and a new building was constructed to house the college. However, as the years progressed, so did the student intake and with pupils now numbering in the hundreds, some were forced to study in the local synagogue. This set up was not favoured by the faculty who decided that a new, larger building, able to hold the entire student roll, was needed. And so it was, in 1912 that the original building was demolished to make way for a new edifice which would be big enough to contain all the students, which at the time exceeded 300. The Chofetz Chaim raised the 15,000
rubles necessary for the task and construction was finished in 1913. The finished building not only included a spacious study hall, but also dormitories, side rooms uses for various functions, a medical room and a library where thousands of volumes were kept. ==World War I==
