- Abstract
- Die vorliegende Monografie ist eine Geschichte der Informationstheorie Claude Elwood Shannons. Die dafür umfangreiche Auswertung bislang unbekannter Primärquellen wäre ohne der Geduld und der Unterstützung vieler Institutionen und Personen nicht möglich gewesen. Etwas mehr als acht Monate intensiver Forschung in verschiedenen Archiven waren nötig, um die Entstehung der Informationstheorie zwischen 1940 und 1949 vergleichend und schrittweise rekonstruieren zu können. Mehr als die Hälfte dieser Zeit war ein vergebliches Suchen in Findmitteln, Karteikarten, Datenbanken und Akten ohne weiterführende Hinweise. Heute - im Rückblick - kann ich verstehen, warum die Geschichte der Informationstheorie bislang noch nicht geschrieben werden konnte: Die Heterogenität der Akten an den unterschiedlichsten Orten, die an den relevanten Stellen geradezu fragmentarische Systematik der Findmittel und die vergangenen Sicherheitsinteressen der Vereinigten Staaten von Amerika während des Kalten Krieges hatten es Historikern bislang noch nicht ermöglicht, die interessante, aber auch geheime Geschichte der Informationstheorie Claude Shannons einer interessierten Öffentlichkeit vorzustellen ...
