Attributing scientific and technical progress: the case of holography

Holography, the three-dimensional imaging technology, was portrayed widely as a paradigm of progress during its decade of explosive expansion 1964–73, and during its subsequent consolidation for commercial and artistic uses up to the mid 1980s. An unusually seductive and prolific subject, holography successively spawned scientific insights, putative applications and new constituencies of practitioners and consumers. Waves of forecasts, associated with different sponsors and user communities, cast holography as a field on the verge of success—but with the dimensions of success repeatedly refashioned. This retargeting of the subject represented a degree of cynical marketeering, but was underpinned by implicit confidence in philosophical positivism and faith in technological progressivism. Each of its communities defined success in terms of expansion, and anticipated continual progressive increase. This paper discusses the contrasting definitions of progress in holography, and how they were fashioned in changing contexts. Focusing equally on reputed ‘failures’ of some aspects of the subject, it explores the varied attributes by which success and failure were linked with progress by different technical communities. This important case illuminates the peculiar post-World War II environment that melded the military, commercial and popular engagement with scientific and technological subjects, and the competing criteria by which they assessed the products of science

Memories of a Dying Industry: Sense and Identity in a British Paper Mill

Frogmore paper mill is a kind of time machine that allows historians of technology and the senses to study mechanized paper-making as it was done one hundred years ago. Before the introduction of instrumentation and automatic process control paper-making depended profoundly on the embodied skills of the workers. This paper will focus on the sensory knowledge and skills required for monitoring and controlling old machinery. Investigating skills-in-use will help to unravel the close link between sensing and acting to keep a continuous production process stable and running. Paper-makers would shift intuitively between different senses and sensory modes of monitoring and diagnosing sensory tell-tales to balance the production process. The importance of sensory knowledge and embodied skills also shaped paper-makers’ self-perception and professional ethos. The paper will examine the impact of new process control technology on the crucial role of sensory skills for the paper-makers’ individual and collective identities
