"I should've put it as "Who killed Buford Lange the first time, before the Hand resurrected him", since he was later (apparently) killed again by someone else.

I'm looking for the person who killed him the first time."

I can't remember his name, but wasn't it his own son?

Was it Wolverine or am I thinking of the 2nd person who killed him?

Who is the Mab Scientist who calls himself The Monster Maker?

Ah, an old Marvel Team-Up storyline I remember well...the guy's name was Baron Ludwig Von Shtupf...his grand idea was to combine parts of Spidey, the Frankenstein Monster and Man-Wolf into an unstoppable army of whatevers.

That is correct! Classic stuff Bedlam in the Balkans. My fave moment is when Spidey easily breaks out of his bonds and frees the Monster. Spider-Man has super strength; something a lot of writers seem to forget. Take it away Dirkzorn.

Yeah, even in the days before TOHOTMU quantified everyone's strength level, I was pretty darn sure Spidey was stronger than Frankie...yet von Shtupf specifically said he wanted his army of monsterlings to have Frankie's strength. Oh well, the fact that he has never returned says volumes about the guy's credibilty level.

New Question: Which old school Inhuman (ie, introduced in the Sixties) had a twin brother?

Black Bolt - his brother is Maximus the Mad

I wonder if their parents named them...imagine having "the Mad" be part of your name when your brother has a cool name like "Bolt"

Black Bolt and Maximus are not twins...Black Bolt is the older brother.

Nope, not twins. It's not one of the Royal Family main Inhuman characters, but, like I said in the question, the character goes back a long way.
