Since the conference on the nationality problem in the Habsburg monarchy was held at Indiana University in April, 1966, two of the active participants whose scholarship and leadership were a source of inspiration to many students of Central European history have died. Each was an active scholar busily pursuing major research projects until the day of his death. Kent Roberts Greenfield passed away less than a week after he returned the corrected galley proof of the article on “The Italian Nationality Problem of the Austrian Empire” published in the second part of this third volume of the Yearbook. He was in the process of preparing an article on American publications in Italian history for the Rassegna storica del Risorgimento. Arthur J. May died the night before he was to tape a television show on the fiftieth anniversary of the U.S.S.R. He had practically completed the manuscript of his history of the University of Rochester and was getting ready to write his long-projected enlarged history of Vienna, based on a vast number of documents collected during numerous trips to that city.
