It was 1973. Readers opened The Amazing Spider-Man #121 expecting the usual. You know the drill: Spidey fights a bad guy, saves the girl, and cracks a joke while swinging into the sunset. But Gerry Conway and Gil Kane had other plans. They didn't just write a story; they ended an entire era of innocence in comic books.
Honestly, the death of Gwen Stacy is probably the most debated moment in Marvel history. People still argue about it at cons and in Reddit threads today. Did the fall kill her? Did the Green Goblin finish her off before she even tipped over the edge? Or—and this is the part that haunts Peter Parker—did Spider-Man actually kill his own girlfriend?

The Night Gwen Stacy Died: The Physics of a Tragedy
If you look at the original panels, the setting is the George Washington Bridge. Fun fact: the art actually shows the Brooklyn Bridge, but the text says George Washington. Marvel eventually fixed this in reprints, but the mistake is part of the lore now. Norman Osborn, back in his Green Goblin persona and fueled by a cocktail of drug-induced psychosis (thanks to his son Harry's LSD relapse) and pure hatred, kidnaps Gwen.
He takes her to the top of the bridge tower. Peter shows up, exhausted and sick with a flu, but ready to fight. During the scrap, Goblin knocks an unconscious Gwen off the edge.
That Infamous "Snap"
Peter reacts instantly. He shoots a strand of webbing. "I've got her, Gwendy! I've got her!" he thinks. He catches her by the leg. For a split second, it looks like a victory. But then, right next to Gwen's neck in a tiny, devastating sound effect box, is the word: SNAP.
Most fans assume the fall or the shock did it. Norman Osborn even taunts Peter, claiming she was dead before the webbing even touched her. He says a fall from that height would kill anyone. He's lying.
In The Amazing Spider-Man #125, editor Roy Thomas laid it out clearly in the letters page. He confirmed that the "whiplash effect" from the sudden stop is what snapped her neck. Basically, the laws of physics were against Peter. Gwen was falling at terminal velocity—about 95 miles per hour. When the webbing caught her, her body underwent a change in momentum so violent that her vertebrae couldn't handle the G-force.
Why This Moment Changed Everything
Before 1973, main love interests didn't die. Not like this. This wasn't a heroic sacrifice or a fake-out. It was a brutal, messy failure. Historians often point to this issue as the official end of the Silver Age of Comics and the start of the Bronze Age. The "Silver Age" was about optimism. The "Bronze Age" was about "real-world" consequences and darker themes.
Gerry Conway, who was only 19 when he started writing Spider-Man, felt that Gwen had become a "dead end" character. She was too perfect. If they stayed together, they’d have to get married, and a happily married Peter Parker didn't fit the "struggling hero" vibe Stan Lee created. Conway wanted to clear the deck for a more complex relationship with Mary Jane Watson.
It worked, but at a massive cost to Peter’s psyche.

The Difference in the Movies
If you've seen The Amazing Spider-Man 2 (2014), you know they tried to recreate this. Andrew Garfield’s Peter shoots a web that literally takes the shape of a hand reaching out. It’s poetic, but the result is slightly different. In the movie, Gwen hits the ground just as the web catches her. You hear a distinct "thud" or "crack" of her skull hitting the floor of the clock tower.
It’s equally tragic, but the comic version is arguably darker because Peter is the direct, physical cause of the injury. He saved her from the water, but his power is what broke her.
Real Talk: Was Peter Responsible?
There's a lot of "what if" games played by fans.
- Could he have dived after her? Probably not fast enough.
- Could he have used multiple web strands to cushion the fall? Maybe, but he was panicking.
- Did he learn from it? Yes. In later comics, you’ll notice that when Spider-Man catches someone falling from a great height, he doesn't just snag a leg. He uses a "web-net" or catches them at multiple points to distribute the force. He learned the hard way that "great power" requires a deep understanding of basic Newtonian physics.
What You Should Do Next
If you want to understand the full weight of this event beyond just a Wikipedia summary, here is how you should dive deeper:

- Read the Original Run: Grab a trade paperback of The Amazing Spider-Man #121 and #122. The second issue, "The Goblin's Last Stand," shows Peter nearly becoming a murderer himself in his grief.
- Check out "Spider-Man: Blue": This limited series by Jeph Loeb and Tim Sale is a beautiful, melancholic look back at Peter's relationship with Gwen. It explains why she mattered so much.
- Watch the Comparison: Look up the side-by-side comparisons of the 1973 comic and the 2014 movie scene. Notice the clock in the movie—it stops at 1:21, a direct nod to the comic issue number.
The death of Gwen Stacy isn't just a plot point. It’s a reminder that in Spider-Man’s world, sometimes doing your best still isn't enough. That’s what makes him the most human hero in the Marvel roster.
