Ihor Ševčenko (1922-2009) died in December of 2009 in Cambridge surrounded by his books and talking with friends around the world. In February 2010 a memorial service was held for him in Harvard, and on its anniversary we held a day in which to reflect on his contribution to Byzantine and Slavonic Studies. It is appropriate that it should be held in Dumbarton Oaks because of his major contribution to the institution as Visiting Fellow (1949050), Professor of Byzantine History and Literature (1965-73) and Director of Studies (1966-67) as well as Dumbarton Oaks Professor of Byzantine History and Literature at Harvard from 1973 until his retirement in 1992. Three Byzantinists and two Slavonicists who were close to him selected one aspect of his wide-ranging oeuvre, commented on its impact upon the field, and then offered something of their own. We hoped that discussion would consist of engagement with the arguments of the speakers, but also of memories of Ihor, scholar of many worlds.
