Hedda MORRISON (1908–1991), née Hammer, was born in Stuttgart, Germany and studied photography in Munich.  She moved to Peiping (Beijing) in 1933 to manage Hartung’s, a German-owned commercial photographic studio and shop in the old Legation Quarter. 

“From 1938 until she and her husband left China in 1946, Morrison worked as a freelance photographer, selling individual prints or thematic albums of her work and creating photographs for other people's books on China. Her photographs document lifestyles, trades, handicrafts, landscapes, religious practices, and architectural structures that in many cases have changed or have been destroyed” (Source: http://hcl.harvard.edu/libraries/harvard-yenching/collections/morrison/index.html).  See Travels of a Photographer in China 1933-1946 (OUP, 1987) and A Photographer in Old Peking (OUP, 1985).  Also  https://en.wikipedia.org/wiki/Hedda_Morrison and http://hdl.handle.net/2027/spo.7977573.0002.206 (Japanese surrender).
