Ferdinand Hurter (born March 16, 1844 in Schaffhausen , † March 5, 1898 in Widnes ) was a Swiss chemist and photography theorist.
Life
Hurter was a son of the art bookbinder Tobias Hurter and his wife Johanna, geb. Öchslin. He grew up in Schaffhausen , went to school there and from 1860 to an apprenticeship in the Jänike fabric dye works in Winterthur . He studied chemistry at the Polytechnic in Zurich and did his doctorate in Heidelberg . In 1867 Hurter moved to England and met the engineer Vero Charles Driffield (1848-1915) at Gaskell Deacon & Company (later Imperial Chemical Industries ) in Widnes . He was a specialist in the Leblanc process for the production of soda and developed the process for the production of chlorine gas with Henry Deacon . In 1886 he became director of Imperial Chemical Industries Ltd. Moon division.
In 1871, Hurter married Hannah Garnett from Appleton, England.

Hurter and Driffield worked together to develop sensitometry and densitometry . In 1890 they published in the Journal of the Society of Chemical Industry their finding that a photographic layer becomes blacker the more light it is exposed to. This theory and its graphic representation in the blackening curve (also density curve or Hurter – Driffield curve ) subsequently simplified photography considerably. A famous saying of his is: "Creating a perfect photographic image is art, creating a perfect negative is science."
