Abraham Dow-Ber, famous for his wisdom, was a son of Józef Berkowicz born in 1825 in Dawidgródek. The boy was remarkably talented and smart. In 1859 he was chosen for the position of rabbi in Kożan-Gródek and later in Lachva (pol. Łachwa). He managed the Jewish Community until 1889. In the autumn of that year he abandoned the synagogue and left for Palestine. Soon after, Abraham Dow-Ber died in Jerusalem, leaving three sons. [1]
