Papers of Sir William Drummond Macdonald Paton, 1930-1993, chiefly comprising papers relating to his main research interests, namely underwater physiology, histamine, synaptic transmission, drug dependence, anaesthetic mechanisms, allergy electron microscopy and the history of science, particularly medical science. The collection also includes correspondence, research papers and laboratory notebooks, and papers relating to the committee work that occupied his energies. Papers from Paton's time as both a Rhodes Trustee and a Wellcome Trustee provide further evidence of the extent of his commitments in committee.

Papers relating to Paton's Chairmanship of the Research Defence Committee (1972-77) are particularly extensive and reveal the social and political pressures of the period, the passionate challenges of the anti-vivisection lobby, as well as Paton's personal commitment to a socially responsible use of animals in scientific experimentation. Papers relating to Man and Mouse: Animals in Medical Research (1984), in which Paton set out his fundamental position on animal experimentation, provide further material on this topic.

Another field of interest in which Paton expended considerable energy was that of drug dependence, particularly the pharmacological action of cannabis. Through work in laboratory and committees, and through the media and many speaking engagements, he campaigned strenuously to warn of what he judged to be the deleterious effects of cannabis, and forged campaign alliances with American colleagues who shared his concerns.

Throughout his career, Paton maintained strong links with the Royal Navy, acting as scientific adviser and consultant on deep diving and underwater physiology. This strand of his work was of enduring interest: Paton's work on the physiological properties of gases at high pressure led directly to the development of the deep-diving breathing mixture known as 'Tri-Mix', in which nitrogen is added to helium and oxygen. Paton took great pleasure in the Royal Navy achieving, in 1980, the world's deepest dive (see D/2/14).
