3 Wright, Basil Martin
SUBJECT AREA: Medical technology[br]b. 20 December 1912 Dulwich, London, England[br]English physician and research physiologist, inventor of the Wright Respirometer peak-flow meter for measurement of respiratory ventilatory capacity and of "fluid lens" spectacles.[br]He qualified at St Bartholomew's Hospital in 1938 and after early hospital posts served in the Army as a specialist in pathology in West Africa and Singapore. In 1947 he joined the Medical Research Council (MRC) and until 1957 he was involved with the Pneumoconiosis Research Unit in investigation of dust inhalation. In 1957 he transferred to the National Institute for Medical Research, to concentrate on instrument development, and in 1969 to the Bioengineering Division of the MRC Clinical Research Centre at Northwick Park Hospital. He was responsible for a number of instrumental developments and inventions in the fields, amongst others, of respiration measurement, blood alcohol levels and variable adjustable spectacle lenses (achieved by altering the curvature of the surface of a thinwalled transparent fluid cell).[br]Principal Honours and DistinctionsFellow of the Royal College of Physicians 1989.

5 Dallmeyer, Thomas Rudolphus
SUBJECT AREA: Photography, film and optics[br]b. May 1859d. 25 December 1906[br]English camera-lens designer.[br]The second son of J.H. Dallmeyer, after graduating at King's College he joined his father's factory, learning lens grinding and optical brass-work manufacture. When his father retired because of ill health in 1882, he took over the business, in which he remained active until his death. He made many improvements in lens design, chiefly in his introduction of the first practical telephoto lens in 1891, for which he received the Progress Medal of the Royal Photographic Society in 1896. He also developed a number of variable focal length lenses, including the soft-focus Bergheim Portrait lens of 1896.BCBiographical history of technology > Dallmeyer, Thomas Rudolphus
