In May 1950 when he left for Vienna, Frey received a letter from Ho Chi Minh, saying, "Dear Mr Nguyen Dan (Frey's Vietnamese name), I felt regret to have been unable to shake your hands. However, wherever you go I'm strongly convinced that you will use what you have in your hands to serve our common cause. I wish you bon voyage and good health."
Frey was born in 1915 in Vienna, Austria. In 1934, he enlisted to join the Communist Youth Union and was detained many times by Austrian fascists.
