Everyone knew in Debrecen, the second most populous city in pre-war Hungary, that the person to go to for an etrog was the respected chassid Reb Wolf Landau. By 1937 his reputation for carrying the most beautiful etrogim had spread so far that people traveled to Debrecen from all the surrounding towns and villages to obtain their etrogim from him. His source was the Greek island of Corfu, whose orchards were prized at the time for the beauty of their produce. Reb Wolf was careful to purchase only from those fields that were supervised by reliable Jews. The Jewish community of Debrecen was devastated by the war, and along with it Reb Wolf’s etrog business came to an abrupt end. But not for good.
