Ernst Cohn-Wiener (until 1907 Cohn), born in Tilsit in 1882, was a versatile art historian who not only dealt with European, Jewish and Islamic art history, but also researched and published on Asian art in general. In particular, his 1930 published work on the architecture of Central Asia in Islamic times is known in professional circles (Turan: Islamic architecture in Central Asia, Berlin 1930), which still has lasting value because of the numerous good photographs from the 1920s.
