author
Known for an early 20th-century account of Turkish life and politics, this writer brought a personal, conversational voice to a moment of huge change in Istanbul. His best-known book reflects both time spent in America and a close view of the Ottoman world in transition.

by bey K. Ziya Mufti-zada
Bey K. Ziya Mufti-zada is the author of Speaking of the Turks, published in New York by Duffield and Company in 1922. The book survives in major public-domain and library records, where he is listed as "Mufti-zada, K. Ziya, bey" or in similar forms.
From the book's catalog descriptions, he appears to write from personal experience, looking back on a return to Constantinople after years in America. That gives his work a memoir-like quality as well as the feel of cultural and political commentary, aimed at helping English-language readers understand Turkish society during a turbulent period.
Reliable biographical details about his life beyond this book were not easy to confirm from the sources I found, so it is safest to remember him as a rare English-language voice presenting an insider's perspective on Turkey in the years just after the First World War.
