Jack Pierce (1889-1968) was the legendary make-up artist responsible for devising and applying the make-up creations for Universal's classic monsters of the 1930s and 1940s. These include Dracula, The Wolf Man, the Mummies, Werewolf of London, Bride of Frankenstein, Ygor, the Man Who Laughs, and the iconic Frankenstein monster.
While there are plenty of comedic behind the scenes photos of Pierce mugging with later Universal horror star, Lon Chaney, Jr., there are very few of the make-up artist clowing around with Boris Karloff. Most of the publicity shots featuring the two of them are straight forward shots of Pierce applying make-up, or at least pretending to, such as the two top photos here.
