Heber Marancenbaum

Heber Marancenbaum's story begins with his father, Arie Marancenbaum, an electrician from Loschitz near Warsaw, Poland. Warned by a well-connected friend that war was coming, Arie left Poland in February 1939, choosing Bolivia largely by chance after Brazil and Argentina were closed to Jewish immigrants. He arrived through Buenos Aires and settled in Santa Cruz, building a livelihood by trading goods despite not knowing Spanish. Nearly all of his family in Poland perished in the Holocaust; only his sister Haya, married to Sol Prangler, survived, having hidden for years in an underground shelter beneath a pig farm belonging to the Catholic Mokinski family. Heber was born in Santa Cruz in November 1948.

Heber trained as a chemical engineer, studying in Mexico from 1966, where a family friend, the Pinsky family, welcomed him for Shabbat and strengthened his connection to Judaism. Returning to Bolivia in 1971, he married Nancy in 1972, and the couple had three children: Ariel, a doctor; Milka, a dentist; and Federico Isaac, who studied political science. Although his father, scarred by the Holocaust, had turned away from Jewish practice while still telling his children stories every night, Heber and his wife chose to build an observant Jewish family, traveling to Buenos Aires around 1978 to formalize their status. He worked as a chemical engineer in Santa Cruz, Cochabamba with the Bata company, and later in La Paz.

With others of his generation, Heber helped form the Jewish community in Santa Cruz, which had no synagogue or cemetery when he was young. The community used a house provided by the Schwarz family for services, brought a rabbi or cantor from Buenos Aires for the High Holidays, and purchased its first cemetery. Heber performed burial services for years and served as the local contact for fundraising campaigns supporting Israel. In 2000 he and Nancy moved to Dallas, drawn by the presence of their children and the beloved Prangler relatives who had long welcomed him during his student years. He remains grateful to the United States, treasures his family ties, and finally fulfilled his wish to visit Israel.
