Stan Lee died yesterday at the towering age of 95.

Before he became the most famous cameo in Marvel’s superhero films–as well as the ‘Big Bang Theory’–Stan Lee was regarded inside the comic book universe as the endless creator of spectacular superheroes and a builder of, well, universes for said superheroes. And like many pop culture icons, Mr. Lee had a surreal impact on countless people’s childhoods.

Along with the adulthoods that grew from those imaginative childhoods.

His blockbuster credits (full and partial) include Spider-Man, the X-Men (Wolverine, Magneto, Professor X, Cyclops, Mystique, Rogue, to name a few), the Avengers (the Hulk, Thor, Iron Man, Captain America, Black Widow, Hawkeye, Loki, to name a few), and Fantastic Four (Dr. Doom, Thing, Susan Storm, Mister Fantastic, Human Torch).

Interestingly, Mr. Lee had a naming quirk regarding his superheroes. Raj pointed this out extensively in an episode of ‘The Big Bang Theory.’

Raj has a point.

More to the point is a simple truth that Stan Lee positively changed lives with his art and boundless creativity fueled by childlike wonder. The following cameo in ‘Spider-Man 3’ sums his legacy up perfectly.

However, a more perfect summary to remember Stan Lee would simply be Excelsior.
