The freezing of a memory: Tribute to Edith Weyde


A book of recent publication pays tribute to the German scientist, discoverer of the processes that allowed the automation of the processes of copy and instant photography

Edith Weyde was a German chemist at the Agfa company in Leverkusen who, together with the Belgian engineer André Rott, created the process of transferring images by diffusion or Diffusion Transfer Reversal (DTR), with the aim of automating the photographic process, was one of the bigger advances in silver copying techniques (silver salts). It is the basic process that allowed the instant photography of companies like Polaroid, Kodak or Fuji and even the origin of the direct electrophotographic reproduction system.

Within this book there is a chapter entitled “Tribute to Edith Weyde” that the director of the International Museum of Electrography (MIDE) has recovered and updated from his Doctoral Thesis: Alcalá, José Ramón (1989) The electrophotographic digital procedure: an alternative to traditional mechanics’ procedures of generation, reproduction and stamping of images for artistic purposes. Valencia. Polytechnic University of Valencia. Pp.418-434.

In this publication, a tribute to Edith Weyde, the students of the subject Cultural Interfaces and New Media of the 2015-16 edition of the Master of Research in Artistic and Visual Practices of the School of Fine Arts of Cuenca have also participated with their works, included in the publication.

Indeed, Alcala had the opportunity to interview Dr. Weyde in Kürten (Germany) in 1988, shortly before his death and deepen the knowledge about these processes, whose experiments were carried out between 1937 and 1938. The visit, with the Researcher and director of Müseum für Fotokopie in Mülheim / Ruhr (Germany), Klaus Urbons, was videotaped and is currently available on YouTube:
