----------------------------Original message---------------------------- A late reply to Darius' request for information about early air photos. The book he is looking for may be: Fluckiger, Otto, 1881-1942. Die Schweiz aus der Vogelschau : 274 Abbildungen aus der Sammlung von Walter Mittelholzer. Herausgegeben und eigeleitet von Prof. Dr. Otto Fluckiger. 2. vermehrte Auflage. Erlenbach-Zurich, Eugen Rentsch, 1926. xxxxiv, 176 p., ill. Thanks to the online catalog of the U.W. General Library System and the retrospective conversion project of the U.W. Geography Library staff (where a copy of the book may be found) for the ease with which it was found! Back in 1967, I gave a paper on the history of aerial photography at an SLA GMD meeting. It was published in the SLA GMD Bulletin, no. 69, p. 17-25. Darius, let me know if you would like a copy. I do not remember the name Mittelholzer from that research, but I do remember finding a lot of information on the topic. Mary Galneder, Arthur H.
