Baron von Krupa

KAOS arms dealer who backed Germany in the two World Wars ("Two flops in a row," as Maxwell Smart puts it).

Von Krupa Explosives Company is the supplier of nitroglycerine used by Frank Lloyd Joshua in his sabotage plots against U.S. space agencies.

The Baron has a photographic memory and never forgets a CONTROL agent. When he recognizes Smart at the Arabian Nights Hotel in Las Vegas he orders his henchmen Martini to eliminate him.

Reality Check: When Max at first guesses that von Krupa is "a German drummer", it is presumably because he is confusing him with the jazz drummer Gene Krupa.
