After the death of his parents, Kaidanow, then just 13, joined an army of Jewish guerrillas who battled the Nazis. He later moved to the United States, eventually opening a series of clothing stores, including some on Eastern Avenue and in Glen Burnie. Today, he lives in Lutherville. He finds strength in his family, he has a wife who gives him a lot of "naches," he said, a Yiddish word meaning "good stuff." His children are very successful; one's a lawyer, the other works in politics.
