In December 1993, the First International Conference on Grey Literature entitled “Weinberg Report 2000” was convened here in Amsterdam. A special tribute was paid to Alvin M. Weinberg, who in the early 60’s chaired President Kennedy’s Science Advisory Committee and produced the famous report “Science, Government, and Information: the Responsibility of the Technical Community and the Government in the Transfer of Information”. Along these lines - a decade later - a special tribute is paid at this Fifth International Conference on Grey Literature to four information professionals, who have had long careers in information, who themselves attended and presented papers at the First International Conference on Grey Literature (GL’93), and who have made lasting contributions to specific areas in the field of grey literature. The four are Vilma Alberani, Italy; Peter Auger, United Kingdom; Ulrich Wattenberg, Germany; and Andrei Zemskov, Russia. Early this summer, each of the four was contacted via GreyNet’s office and asked to provide bibliographic, autobiographic and other human-interest reference material in an effort to gather firsthand information for the paper and its subsequent presentation.
