I just stumbled on this interesting quote from Ian Fleming, the author and journalist best remembered for his James Bond 007 series:
“James Bond is a highly romanticized version of a true spy. The real thing is…William Stephenson.”
–Ian Fleming, The Times, October 21, 1962.
A quick search for William Stephenson came up with this:
Stephenson was born William Samuel Clouston Stanger on January 23, 1897 in the Point Douglas area of Winnipeg, Manitoba in Canada. … was a Canadian soldier, airman, businessperson, inventor, spymaster, and the senior representative of British intelligence for the entire western hemisphere during World War II. He is best-known by his wartime intelligence codename of Intrepid.
