I wish to offer my sincerest thanks to all the individuals and organizations in Turkey and abroad who helped by providing me with information and guidance in the course of my research into a great master of the art of photography whose work has, for nearly a century or more, been neglected and all but forgotten. Beginning with those outside Turkey, I want to thank Professor Heinz Henisch, the founder of the Department of the History of Photography at Pennsylvania State University, and his wife Bridget Henisch; Professor John Wood, chairman of the Department of the History of Photography at McNeese University; Beth Ann Guynn of the J. P. Getty Foundation Institute for Research; Joseph Struble of the George Eastman Museum of the History of Film and Photography, and Greg French. Similarly I owe a debt of thanks to Eva Wisehn of the Medals section of the Swedish Royal Museum; Anna Meister of the Swedish Prince Eugens Waldemarsudde Museum; Leif Wigh of the Swedish Museum of Photography; Joergen Steen Jensen of the Medals section of the Danish Royal Museum; Professor Leopold Auer, director of the Austrian State Archives; Uwe Schögl of the Photographic Archives of the Austrian National Library; Bernard Marbot, director of the Department of Photography of the National Library in Paris, and also Ahmet Abut, Pierre de Gigord, Gerard Levy, Zafer Ataman, and Fouad Debbas; and to Ronnie Margulies in London.
