Felix Russell ENGDAHL (aka Russ) [1907-1942]

From http://lifeafterjerusalem.blogspot.co.uk/2009/04/foreign-affairs-day-and-plaque-ceremony.html:

Felix Russell Engdahl (July 28, 1907-May 14, 1942), better known during his life as Russ Engdahl, joined the Foreign Service on December 16, 1930. After serving as Vice Consul in Port-au-Prince and Calcutta, Engdahl was assigned to Shanghai in October 1935. He was promoted to Consul and, in late 1941, traveled to Hong Kong on courier duty. He was captured by the Japanese not long after the fall of Hong Kong in late December 1941, along with several other members of the Foreign Service and sent to the Stanley Internment Camp. Engdahl died in the camp on May 14, 1942, a few months before all Americans in the camp were repatriated. His death was accidental, caused by a fall down some stairs while in the prison.
