Sir William de Wiveleslie Abney

Abney, Sir William de Wiveleslie (1843-1920), influential British photographic scientist whose early interest in photography was encouraged by the army while he was a junior officer in the Royal Engineers. Following service in India, Abney became an instructor in chemistry and photography at the School of Military Engineering, Chatham, a post that allowed him to undertake photographic research and devise a new photolithographic printing process. He left Chatham in 1877 to become a civil servant in the Department of Science and Art, where he soon became a major figure in British photography.

Abney undertook significant research on the chemistry of the newly introduced gelatin halide emulsions and was responsible for the introduction of hydroquinone as a developing agent. His introduction of silver gelatin citrochloride emulsions led to the mass marketing of printing-out paper (POP). He was a prolific author, writing for both specialist practitioners and amateurs. It was Abney who was largely instrumental in establishing a photographic collection at the South Kensington Museum, later to become the Science Museum Collection and form the basis of the National Museum of Photography, Bradford.

William de Wiveleslie Abney FRS (July 24, 1843 - December 3, 1920) was an English astronomer, chemist, and photographer.

Biography

Abney was born in Derby, England, to a clergyman father. He attended the Royal Military Academy, Woolwich and joined the Royal Engineers in 1861, with whom he served in India for several years. Thereafter, and to further his knowledge in photography, he became a chemical assistant at the Chatham School of Military Engineering.

Abney was a pioneer of several technical aspects of photography. His endeavors in the chemistry of photography produced useful photographic products and also developments in astronomy. He wrote many books on photography that were considered standard texts at the time, although he was doubtful that his improvements would have a great impact on the subject.

Abney investigated the blackening of a negative to incidental light. In 1874, Abney developed a dry photographic emulsion, which replaced "wet" emulsions. He used this emulsion in an Egyptian expedition to photograph the transit of Venus across the sun. In 1880, he introduced hydroquinone. Abney also introduced new and useful types of photographic paper, including in 1882 a formula for gelatin silver chloride paper.

Abney conducted early research into the field of spectroscopy, developing a red-sensitive emulsion which was used for the infrared spectra of organic molecules. He was also a pioneer in photographing the infrared solar spectrum (1887), as well as researching sunlight in the medium of the atmosphere.

Abney invented the "Abney Level", a combined clinometer and spirit level, used by surveyors to measure slopes and angles.

He died in Folkestone, England.

Quotes

  • "[...] whatever little notions of art a person might have in his head would certainly be driven out of it, for the knowledge that he could take an almost unlimited number of pictures would lead him to expose a sheet on every possible occasion, and probably 99 percent of what he obtained would be thoroughly inartistic productions".
