What a riveting discovery. Portrait of a Turkish Family, by Irfan Orga was a book neither my wife nor I could put down once we started it. Orga is such a graceful writer, and yet English was not his native language. Born in 1908, he recalls the charm of Old Istanbul and tells the story of how his upper class Turkish family went from wealth to poverty and near-starvation during World War I and the fall of the Ottoman Empire, only to resurrect itself and yet suffer more ups and downs through the 1940s. Orga knew Mustafa Kemel (Ataturk), but the focus of this book is his intimate family relationships: grandfather, grandmother, father, mother, brother, sister, as well as his experiences in military school. This book helps me to understand what the Turkish people experienced in the first half of the 20th century. I'd like to read more books by the author. Irfan Orga is a fascinating character.
