Edward Constant II (born 1942/43) is a former Professor of History at Carnegie Mellon University, and convicted of aggravated assault and attempted homicide.
In 1982 he was awarded the Dexter Prize of the Society for the History of Technology (SHOT) for his book titled "The Origins of the Turbojet Revolution.
In 2004 was convicted by an Allegheny County jury trial of attempted homicide and aggravated assault.
The officer was shot in the chest by a .44 caliber Smith & Wesson revolver, but survived the attack because he was wearing a bullet-proof vest.
The first trial was overturned after a juror came forward to report that Judge David Cashman's tipstaff, Mary Feeney, made inappropriate comments that could have swayed the panel.
