Gunther Fischer - Böcker

Stability is one of the most important performances required for silver halide photographic materials. In 1935, Dr. E. 1. Birr introduced the concept of the stabilization ofphotographic emulsions for the first time by inventing a most effective stabilizer, 4-oxo-6-methyl-l,3,3a,7-tetraazaindene (TAl). Dr. Birr's monograph Stabilization ofPhotographic Silver Halide Emulsions was published in 1974,and accepted as a reliable reference book by many photographic scientists and engineers. Since then, silver halide photographic materials have been greatly improved and expanded through active and continual development of various kinds of technologies. Especially, extensive efforts have been made to develop photographic materials with high sensitivity and rapid processing, which rely upon the stability ofphotographic emulsions under various conditions. Thus, the concept and technologies of stabilization ofphotographic silver halide materials have been expanded so extensively that many photographic scientists and engineers eagerly want a reliable, new reference book on the stabilization of photographic emulsions. Dr. Gunther Fischer is one of the most experienced and eminent scientists and engineers in the field of the stabilization of photographic materials with expanded concept. He has been involved in research on the stabilization of pho­ tographic emulsions since 1964 when he joined the Technical Scientific Laboratory in the Research and Development Department of the Photo Film Company Agfa Wolfen formerly headed by Dr. Birr, whom he succeeded in that position. I was deeply impressed by his fruitful and elaborate achievements in these fields.

A fast-moving summary of the history of architecture, retold as the story of a remarkable transformation: from the architecture of antiquity to a new beginning in the Renaissance, and from the evolution of modern architecture to the present day and possible future developments.This approach represents the only way to gain clarity about the state of current architecture and its confusing manifestations seeking to understand the overall relationship between the ancient art of building and modern architecture and thus regarding the whole of architecture in a new light. It becomes evident that both manifestations, despite all the breaks between them, constitute a single, coherent field. Look inside 25 years of architectural history in one volume Opulently illustrated edition with over 4 iconic illustrations The amazing transformations of architecture are not only described, but also explained

Vitruvs Zehn Bücher über Architektur sind bislang vorrangig unter kunsthistorischem Blickwinkel übersetzt und rezipiert worden, obwohl sich das Werk immer gegen diese Lesart gesperrt hat und unter solchen Prämissen widersprüchlich, unklar und undurchdacht erscheint. Vitruv war aber Architekt, kein Kunsthistoriker. Liest man seinen Text dementsprechend als Theorie des Fachs Architektur, tritt auf einmal eine völlig schlüssige und nachvollziehbare Architekturtheorie hervor, die auch der aktuellen Diskussion entscheidend neue Impulse zu geben vermag. Günther Fischers revidierte Übersetzung und Interpretation der theoretischen Kapitel dieses klassischen Textes eröffnet die Chance, die Kolonisierung des Fachs durch den kunstgeschichtlichen Blick rückgängig zu machen. Sie entdeckt Vitruv wirklich neu: nicht als Kunsttheorie, sondern als genuine Architekturtheorie.
