Professor Sadi is MacGyver's old Archeology professor. Considered by MacGyver as one of the last Swashbuckling archeologists he was more at home with thieves and smugglers than academics, he over saw a dig in Turkey which MacGyver took part in as a student and, in MacGyver's own words, "he taught me some of the more colorful ways to discover history." Since moving on from teaching Archeology he is now a curator at the Cairo Museum.
MacGyver visited the Professor while on the hunt for Pierre Lamont
. It was the professors information and archeological dig journals which gave MacGyver Pierre's real name of Claude Martell
