In Code Bernard Dionysius Geoghegan reconstructs how Progressive Era technocracy as well as crises of industrial democracy and colonialism shaped early accounts of cybernetics and digital media by theorists including Norbert Wiener Warren Weaver Margaret Mead Gregory Bateson Claude LviStrauss Roman Jakobson Jacques Lacan Roland Barthes and Luce Irigaray. His analysis casts light on how mediapractical research forged common epistemic cause in programs that stretched from 1930s interwar computing at MIT and eugenics to the proliferation of seminars and laboratories in 1960s Paris. This mobilization ushered forth new fields of study such as structural anthropology family therapy and literary semiology while forming enduring intellectual affinities between the humanities and informatics.
