Rivka Guber (née Bumaghina) was born in Novo-Vitebsk in the Ukraine and went to high school in Yekaterinoslav (Dnipropetrovsk) intending to continue her studies at university. The outbreak of the revolution disrupted her plans and forced her to return to Novo-Vitebsk where she worked as a teacher. In 1920 she married Mordecai Guber, who was born in 1893 in the town of Gorodik near Bialystok. They immigrated to Palestine in 1925. The couple settled in Rehovot, where Mordecai taught Hebrew. They were among the founders of Kefar Bilu (1933), later leaving to join Kefar Warburg, where they raised their two gifted sons, Ephraim (b. 1927) and Zvi (b. 1931).
