Duke Richard of York's intentions in I450 and the origins of the wars of the roses

The return of Richard, duke of York, from Ireland in 1450 represents his first overt attempt to remedy certain grievances. His criticism of the Lancastrian régime eventually brought him leadership in the Wars of the Roses. The grivances of 1450 are contained in two bills addressed to Henry VI. At first, the duke harboured personal grievances — fear of attainder and having his claim to the throne bypassed, resentment at his counsel being ignored and his debts unpaid — which were exaguerated by unsertainty and the king's readiness to believe the worst. Richards apreciation of the widespread hostility towards the government and the disarray of the king's Household after Suffolk's murder enabled him to convert grievances into public criticisms in his second bill. He encouraged investigations into official oppression in southeastern England, and his supporters may have stimulated risings there to demonstrate support for him. Compared with Henry's nervous reaction to York's first bill, he firmly checkmated the pretensions of the second, and Yorks achievement in 1450 was limited. But he had taken a first step towards appealing for support by converting personal grievances into a general bid for sympathy. Whether he aid so for personal or public motives — or both — remains an open question.     

Attributing Scientific and Technological 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.
