What is the significance of Victor's name?
I was going to answer your question focusing on the name "Victor" because the Victor of this story is no victor. He creates a monster out of pride and the desire to make himself famous, but his creation, the monster, winds up destroying him. He therefore is not the "victor" in life because his creation is a failure, and he is not a "victor" in his relationships with people either. You can read about the themes of this story here on enotes to find others ways in which Victor is is NOT a "victor".
When I was doing a bit of research for this question, however, I found that "franken" is a prefix that means "genetically engineered" - and I didn't know this, so I learned something today myself! Obviously, the monster was kind of "genetically engineered" -- at least, he was engineered in such a way that was not normal, not human. So this adds another dimension to the name Victor Frankenstein.
The word "frank" also means truth, and Victor strays very far from the truth. Check out the "themes" link on the Frankenstein page below.
