He established a large yeshiva in Novorodock and was responsible for creating a whole network of yeshivas. Reb Yosel believed that abnormal times required a radical approach which demanded total immersion in spiritual matters without consideration for the amenities of existence. His major work is appropriately named Stature of Man. In 1919, while he was in Kiev, a plague broke out and while caring for the sick, Reb Yosel himself became ill and succumbed on the 17th day of Kislev.
