The man standing behind CKS with his head down was Australian journalist WH Donald. He was a good friend of Madame Soong and probably very helpful in writing press releases for the USA media detailing CKS’ struggle against the Japanese and later the commies. WH Donald had a state funeral courtesy of the KMT and was in their very good friends category.
A website detailing his history is at: http://donaldofchina.com
