André Grabar

André Nicolaevitch Grabar (; July 26, 1896 – October 5, 1990) was a historian of Romanesque art and the art of the Eastern Roman Empire and the Bulgarian Empire. Born and educated in Kiev, Saint Petersburg and Odessa, he spent his career in Bulgaria (1919–1922), France (1922–1958) and the United States (1958–1990). Grabar was one of the 20th-century founders of the study of the art and icons of the Eastern Roman Empire, adopting a synthetic approach embracing history, theology and interactions with the Islamic world.

His son Oleg Grabar also became an art historian, with a special interest in Islamic art and architecture. Provided by Wikipedia
