Edith Weyde

Edith Weyde (17 September 1901 – 10 February 1989) was a German chemist.[1] She developed the silver salt Diffusion transfer—"Copyrapid"—which paved the way for the first photocopiers and instant photography.[1][2][3][4][5] She also laid the foundation for color photography.[1][3][4]

Edith Weyde

Early life and education

Weyde was the second child of an Austrian grammar school teacher in Prague.[1] She grew up in Aussig and finished her Abitur in 1919.[1] Then, she worked for four years as a laboratory assistant for the Verein für chemische und metallurgische Produktion.[1] In 1923, she began studying chemistry at the Technical University of Dresden.[1] Four years later, she finished her doctorate with Robert Luther at the Photographic Institute of the Technical University of Dresden.[1]

Professional life

Weyde started her first job in the photographic-photochemical laboratory of I.G. Farbenindustrie AG in Oppau in 1928.[1] After four years, she was transferred to the Agfa photo-paper factory in Leverkusen.[1] She worked on improving the tropical suitability of photographic paper and for this purpose developed stabilizers for the photographic layers.[1] She was involved in the development of the first Agfacolor papers from 1937 and contributed to the success of early color photography.[1][3]

Inventions

Weyde developed the silver salt Diffusion transfer method—also called "Copyrapid"—which was a process for the accelerated production of a photographic positive image according to an original.[1][2][6] This led to the development of photocopiers, instant film and instant cameras.

Awards

Also, a street in Leverkusen is named after her.[11]
