《欧洲教育》2013,45(3):94-95
The publisher and the editorial staff of Western European Education express deep sorrow at the passing on October 22, 1983, of Professor George Z. F. Bereday, who served as a member of the quarterly's Advisory Board since the founding of the journal in 1969. A close friend, colleague, and collaborator of the Editor, he made helpful suggestions for the benefit of WEE. He was a nationally and internationally influential scholar and educator, a most effective and inspiring instructor, a successful supervisor of significant doctoral dissertations, energetic editor and writer, a specialized lawyer, a soldier in the struggle against totalitarian tyranny, and selfless in his service for the welfare of his community, nation, and world.  相似文献
