Further information: Dr Russell J. Reynolds (1880-1964) was a pioneer in the field of cineradiography. Throughout the 1900s his career spanned the development of radiography both as a therapeutic and a diagnostic tool. Examples of his earliest experimental work in cineradiograhy in 1921 are held by the BFI National Film and Television Archive, London. This example was given to the BMA by the Physiological Society, which was then acquired by Wellcome LIbrary in 2005.
