Dr. Frankenstein's assistant (4)

I believe the answer is:

igor

(Other definitions for igor that I've seen before include "Stravinsky, for example" , "Stravinsky, perhaps" , "Prince in Borodin's opera" , "Stravinsky's first name" , "Prince of grand opera" .)

I've seen this clue in the Universal and The New York Times.
