comic book deaths

me and my cousin were talking about deaths in comics today they are more or less meaningless but some do have impact i myself was upset t see the blue elf nightcrawler kick the bucket (until recent times)

we were talking about who was the first comic book hero to die as far as i know its captain marvel....

the ost to die i think is jean grey....

my question is who was the first to die, who has been dead the longest,who has died the most, whe has died and stayed dead the longest?

The longest I think was Jean.

Well the earliest death would be Lara and Jor-El followed by the Waynes.And they have been the longest deaths in comic books.

Uncle ben has been a really long death
