During World War II, James C. M. LO 羅寄梅 (1902–1987), a photojournalist for the Central News Agency, and his wife Lucy 劉氏·羅先 arrived at Dunhuang.  James Lo had taken a year’s leave to photograph the Buddhist cave temples at Mogao and at nearby Yulin.  Lucy was also a photographer, and together they made the arduous journey in 1943.  They systematically produced over 2,500 black and white photographs that record the caves as they were in the mid-20th century.  Source: IIAS Newsletter 73 (Spring 2016).
