The Seattle Times published the mystery man's photo on its Web site, and reader David Akast called the paper Thursday to say he is Edward Lighthart.
The man ? in his 50s and fluent in French and German ? had $600 hidden in his sock when he flagged down a bus July 30 wearing khakis, a dress shirt and a blazer.
He believes he went to the University of Wisconsin in the 1980s, studied at the University of Chicago and Columbia University and lived in Paris, Vienna, Sydney and Shanghai.
Three psychiatrists who examined him in Seattle recently believe the amnesia is genuine.
