It was the Chicago Tribune of June 13th, 189-, which contained this paragraph under the head-line: Big Broker Missing! The friends of Isidor Werner, a young man prominent in Board of Trade circles, are much concerned about him, as he has not been seen for several days. He made his last appearance in the wheat pit as a heavy buyer Tuesday forenoon. That afternoon he left his office at Room 87 Board of Trade, and has not been seen since, nor can his whereabouts be learned. He is six feet two inches high, of athletic build, with black hair and moustache, a regular nose, and an unpronounced Jewish appearance. His age is hardly more than twenty-seven, but he has often made himself felt as a market force on the Board of Trade, where he was well thought of.
