New York Stock Exchange

This guide to the New York Stock Exchange centers on midday, September 16, 1920, when a horse-drawn wagon stood parked at the corner of Wall and Broad Streets while the lunchtime crowd streamed out of the surrounding buildings. It follows what happened next, the exchange's calm response as trading was halted, and the investigation into who was behind it, including a suspected Italian anarchist tied to the Sacco and Vanzetti case. Look across the street at the pocked stone facade of 23 Wall Street as you listen.
