Eugene Garfield
Eugene Garfield (* 16. September 1925 in New York) - Wissenschaftler und einer der Begründer der Bibliometrie.
Er studierte an der Columbia Univ. und machte dort 1949 seinen ersten Abschluss (B.S.) in Chemie, 1954 seinen zweiten Abschluss (M.S.) in LIS. 1961 promovierte er im Fach Linguistik.
Ab 1955 war er als Berater für pharmazeutische Unternehmen tätig und spezialisierte sich auf Fachinformation, indem er CurrentContents? (Inhaltsverzeichnisse relevanter Fachzeitschriften) erstellte. In einem Aufsatz in der Zeitschrift Science (Band 122, Nummer 3159, Seite 108 - 111) schlug er 1955 vor, Zitationen wissenschaftlicher Veröffentlichungen systematisch zu erfassen und damit Zitationszusammenhänge deutlich zu machen. 1960 gründete er das Institute for Scientific Information (ISI), dessen CEO er bis zu seiner Pensionierung 1992 blieb. ISI erstellt Datenbanken, zB den Science Citation Index / Web of Science / WOK. Aufgrund seiner großen Verdienste wurde er mit zahlreichen Ehrendoktortiteln ausgezeichnet.
