It may be a bit of hyperbole to call it that, but Superman couldn't think straight without it, and without it Batman might as well call himself Bruce and fight crime in a tuxedo. And its inventor is indeed one of the richest men in American.
Who is he?
Wayne Blitzstein, the inventor of the comic book "thought balloon."
Prior to Blitzstein's dazzling innovation, all characters in comic books thought in the same manner in which they spoke. A word balloon coming to a sharp point directed straight at each character's head was used for both thought and speech. Consequently every character in every comic book knew exactly what each other was thinking!
Pandemonium ensued. Commissioner Gordon, the Joker, the Penguin, and every other resident of Gotham City knew Batman's secret identity, rendering him far less effective as a crime fighter. Mostly he just gave out parking tickets and posed with Dorothy Lamour. Superman, for his part, was constantly being slapped by Lois Lane whenever he gave her the once-over with his ex-ray vision, causing her to break her hand in every edition of Action Comics until the early sixties!
The worst impact of the so-called Uni-Balloonular System of Comic Art was visited on the romance genre of the comic book. Since characters kissing passionately had to think in the same word balloons they were speaking, their thoughts could consist of nothing more than:
Gradually romance comic books became almost as sappy and infantile as CNN's approach to news reporting.
Assigned to work on Wonder Woman in the late 1950's, Wayne Blitzstein was rapidly becoming sick of drawing uni-balloons with the words "stop thinking about my tits!" One night while chewing bubble gum and thinking "maybe if I took her down a cup size or two," Blitzstein blew a bubble and made a connection: thoughts could be separately depicted by a series of bubbles leading to a word balloon, and the sharp pointed balloon reserved for speech!
Comics were revolutionized! Batman was able to think about how he hated his implausible runt of a sidekick while beating the crap out of the Joker, Lois Lane's hand healed and she grew neurotic and unstable over whether or not Superman dug her, and romantic comic book leads could finally smooch while thinking more mature plot-driven thoughts, such as ....
She: "I wonder if he knows I'm cheating on him with fully two-thirds of the Green Bay Packers?"
He: "I wonder if she knows I'm cheating on her with fully two-thirds of the Green Bay Packers?"
How does he feel about his place in the history of the comic book?
Who knows? He always thinks in thought balloons.
"Mmm-Wahhhh! Mmmm-Wahhhhhh!" no more
