David was an exchange student from Australia. A number of our classmates remained friends with him all these years. David was a very accomplished citizen of Australia. He was their ambassador to China for several years. Please read his profile. (A side note: we shared the exact same birthday)
From his profile:
After leaving Havertown in 1965, I returned to Western Australia, completed an Arts degree and then joined the Australian Foreign Service in 1970. I served overseas in Italy, Indonesia (twice), Hong Kong, China (twice) and Papua new Guinea. I was Australian High Commissioner in Papua New Guinea from 1996-1999 and Australian Ambassador to China from 2000-2003. During those latter China years, I was also Ambassador the North Korea and to Mongolia. I headed the Australian Secret Intelligence Service from 2003-2009 and was Director-General of Security in charge of the Australian Security Intelligence Organisation from 2009 until my retirement in September 2014.
My wife, Robin, and I live in Canberra, Australia, but have been able to visit the United States frequently with my work and hope to do so in a more leisurely fashion now that I have retired.
