“In Aleppo Once” is a 1969 memoir by Taqui Altounyan, who spent most of her young life in the ancient Syrian city of Aleppo, where her Armenian father and grandfather were doctors and her grandfather was revered because he established its only hospital after World War I. He had studied medicine in New York, coming to the United States with the help of American missionaries he had met during the Armenian genocide. Altounyan’s mother was an Englishwoman.
