Stevens

Abbott and Costello Meet Frankenstein
Doctor Stevens, also known as Professor Stevens, is a fictional scientist and a supporting character in the Universal Monsters film series. Played by actor Charles Bradstreet, he appeared in the 1948 horror/comedy, Abbott and Costello Meet Frankenstein.

Doctor Stevens was the assistant of Doctor Sandra Mornay and Doctor Lejos and worked out of Lejos' laboratory in La Mirada, Florida. When Lejos revealed himself to be the vampire Dracula, Doctor Stevens helped Larry Talbot and Chick Young rescue their friend Wilbur Grey.

Stevens was a member of the United States Army. Along with another soldier named Brewer, he went on a scouting mission to Simmonsville, Nevada under the orders of Major Vale. Simmonsville was a town composed entirely of psychoplasm, which is the ethereal substance of Hell. The town, named for former soldier Al Simmons, was a collage of aspects from Simmons' memories.

Stevens compared the idyllic setting to Disneyworld, noting how everything seemed artificial and out of place. As Stevens and Brewer surveyed the area, aspects of several demons from Hell rose up and slaughtered them.
