->''"I like nonsense, it wakes up the brain cells. Fantasy is a necessary ingredient in living. It's a way of looking at life through the wrong end of a telescope, which is what I do, and that enables you to laugh at life's realities."''

An American cartoonist and writer, Theodor Seuss Geisel (March 2, 1904 September 24, 1991), more commonly known as Dr. Seuss ([[NoPronunciationGuide pronounced "soyss" like "voice," although he later accepted "sooss"]]), was famous for his 65 children's books.

Most of his work liberally uses [[RhymesOnADime rhyming schemes]], [[MagicAIsMagicA illogical logic]], [[{{Bizarrchitecture}} fantastical buildings]], [[PerfectlyCromulentWord nonsensical vocabulary]], and very pretty illustrations. This, at the time, was fairly radical and the epitome of avant-garde, though [[SeinfeldIsUnfunny not by today's standards]]. Seuss was a lifelong inhabitant of Springfield, Massachusetts, and drew inspiration from his surroundings; for instance, ''And to Think That I Saw It on Mulberry Street'' took place on [[WriteWhatYouKnow a real life street.]] (The book's events occur on the intersection of Mulberry and Bliss Streets, which both exist. However, the real-world versions never cross.)

Besides his children's work, Seuss was a political cartoonist, most notably for the now-defunct magazine ''PM''. He was a committed New Dealer and supporter of UsefulNotes/FranklinDRoosevelt, and liberal causes generally. On the less savory side, while he [[http://www.k-state.edu/english/nelp/childlit/seuss/10922.html opposed]] anti-semitism and segregation, Seuss is also known for being [[WartimeCartoon quite racist towards Japanese]] in his WWII-era political cartoons ([[http://www.dartmouth.edu/~hist32/History/Seuss02.jpg here's]] an example). He later realized such work was inappropriate and [[OldShame felt horrible about it]]. He was against Jim Crow, even basing one book on getting over [[SillyReasonForWar small differences]] (also dedicating ''Literature/HortonHearsAWho'' to a Japanese friend). He would probably enjoy that hand-drawn, {{Animesque}} spoof in the 2008 ''Horton'' movie quite a lot!

Speaking of which, much of his work has been [[TheFilmOfTheBook movie-fied]], whether by animation or live-action. The only movie he himself made was ''Film/The5000FingersOfDrT''. He did collaborate with various directors (most famously, Creator/ChuckJones) in adapting his stories for television, but again, those were TV specials, and not feature-length. When he passed away, the rights to all his stories and characters went to his widow, and no adaptations could be made unless she approved it. After the dismal 2003 adaptation of ''Film/TheCatInTheHat'' soured her for the casting of Creator/MikeMyers (whom she was strongly against) and the adult jokes that clashed with the family friendly nature of the books, she declared that any future film adaptations of Seuss books must be animated.

There's also ''Seuss Landing'', a portion of [[Ride/UniversalStudios Universal's Islands of Adventure]], which features rides, costumed characters and other attractions based on the books.

Also, [[HeAlsoDid he seems to be the guy who invented the word]] "{{nerd}}". [[note]]It first appears in ''If I Ran the Zoo'', describing a frowning {{Muppet}}-like creature that has nothing to do with the word's modern definition.[[/note]]

He is the subject of the fourth book by pop culture legend biographer Brian Jay Jones, after Washington Irving, Creator/JimHenson, and Creator/GeorgeLucas.

!!Dr. Seuss and his books provide examples of:

%%* AdaptationDistillation: ''Horton Hears a Who''.
%%* AdaptationExpansion: All of the feature films and most of the TV specials.
* AnimatedAdaptation: Numerous, including two feature films.
* AerithAndBob: In ''The 500 Hats of Bartholomew Cubbins'' there is Bartholomew Cubbins, King Derwin, Mr. Snippets, Alrec and the Grand Duke ''Wilfred''.
* AnAesop: Most books that aren't simple rhyming books contain one (notably ''The Lorax'', ''The Butter Battle Book'', ''Literature/GreenEggsAndHam'', ''Oh, The Places You'll Go!'', and ''Did I Ever Tell You How Lucky You Are?'')
%%* BarbieDollAnatomy: ''The Seven Lady Godivas''.
* BewareTheNiceOnes: Surprisingly, involving Horton in a long lost story, ''Horton And the Kwuggerbug'', where a Kwuggerbug takes advantage of Horton's kindness, asking Horton to give him a lift to a beezelnut tree, with the promise of splitting half the nuts with him. The journey proves to be incredibly dangerous, and Horton is tempted to go back, but the Kwuggerbug reminds him that [[IGaveMyWord a deal's a deal]] and to keep going. When they finally get there, the Kwuggerbug ends up stiffing Horton by only giving him the shells, taking the good parts for himself. Enraged, Horton [[SneezeOfDoom sneezes]] blowing the bug so far away, he's never able to return to the beezelnut tree again.
* BittersweetEnding: A number of books, but ''[[Literature/TheSneetchesAndOtherStories The Sneetches]]'' is a prominent example. In the end, [=McBean=] successfully cons the sneetches out of all their money with his Star Machine gambit, leaving them penniless, but the experience teaches them how stupid and pointless racial discrimination is and learn to live as equals from that point on.
* {{Bowdlerise}}: In ''The Lorax'', the Lorax's line, "I hear things are just as bad up in Lake Erie," was removed from the book in 1985 after two research associates from the Ohio Sea Grant Program wrote to Seuss about the clean-up of Lake Erie. However, the same line is still kept in the 1972 TV AnimatedAdaptation (it is spoken by one of the Humming Fish), even in the VHS and DVD releases.
* CartoonBugSprayer: An ad campaign drawn by Dr. Seuss for Flit brand insecticide featured people facing down improbable creatures with this style of sprayer, with one character always exclaiming the slogan, "Quick, Henry, the Flit!" The ads were wildly successful and doubtless contributed to the Flit-style bug sprayer persisting as a stock cartoon image long after the technology fell out of use in real life.
* CastsNoShadow: Harry Haddow in ''Did I Ever Tell You How Lucky You Are?''
-->He thinks that, perhaps, something's wrong with his Gizz,\\
and I think that, by golly, there probably is.
* {{Catchphrase}}: Horton the Elephant has two: "A person is a person, no matter how small." (''Horton Hears A Who'') and "I meant what I said and I said what I meant. An elephant's faithful 100%." (''Horton Hatches the Egg'').
* CerebusSyndrome: Sometime around the late '60s/early '70s, Seuss began writing darker stories like ''I Had Trouble in Getting to Solla Sollew'' and, eventually, ''Literature/TheLorax'', which featured more abundantly heavy themes than his previous books and [[BittersweetEnding not always]] [[DownerEnding the happiest of endings]]. Not coincidentally, this began after [[RealitySubtext his first wife committed suicide]].
* CoolOldGuy: The fellow who the {{narrator}} of "Did I Ever Tell You How Lucky You Are?" meets in the Desert of Drize, who, well, tells him how lucky he is.
* ConjoinedTwins: The Brothers Ba-zoo in ''Did I Ever Tell You How Lucky You Are?'' are conjoined by their ''hair''.
** This concept appeared earlier in Dr. Seuss's work, as well.
* CoolAndUnusualPunishment: Droon is forced to eat nothing but Nizzards at the end of ''The King's Stilts''.
* CosmicHorrorStory: ''Bartholomew and the Oobleck'', if you think about it. A greedy person bored with ordinary life orders his magicians to [[DugTooDeep summon new weather]], which results in the arrival of an ambiguous, borderline-unstoppable phenomenon of potentially apocalyptic proportions. The only thing holding it back is the presence of AnAesop about saying sorry, and even then the closing lines about the current weather being the only things that ever should be is subtly sinister.
* CreatorCameo: In ''Literature/TheresAWocketInMyPocket'', the Bofa on the Sofa (who the narrator wishes wasn't there) looks very Ted Geisel-ish.
* CreatorProvincialism: Seuss lived in Springfield, Massachusetts for the entirety of his youth and drew inspiration from his surroundings. Springfield is mentioned in several of his works (most notably ''Mulberry Street'') and some of his illustrations are [[http://tinyurl.com/l8mo4e9 surreal versions of real places in town]]. Today the Springfield Museums have, in a courtyard behind the city's central library building, an outdoor shrine to him that includes statues of him and various characters, as well as a giant book statue containing the entire text of ''Oh, The Places You'll Go''. There is also a Seuss museum, which is largely a childrens museum but has sections in the upper floors with his papers and other work... though not his World War Two cartoons.
* DarkerAndEdgier:
** ''Literature/TheLorax'' is this compared to the other books. It teaches about the consequences of not acknowledging natural resources until they are gone.
** Even more so, ''Literature/TheButterBattleBook'' is a parable about the nuclear arms race between the US and the USSR, represented by two tribes living on opposite sides of a wall analogous to the Berlin Wall, concluding with a BolivianArmyEnding as the two sides are about to drop their bombs.
** His work as a political cartoonist during World War Two was this, dealing with real world issues about supporting the Soviet Union against the Nazis and supporting Japanese internment. Seuss would later regret the latter.
* {{Determinator}}:
** Sam, who keeps trying to get his friend to try green eggs and ham after being rejected countless times.
** Horton is always faithful, one hundred percent.
** The Lorax gets a speech that illustrates this well in his book's 1970's AnimatedAdaptation.
--> I speak for the trees! Let 'em grow, let 'em grow!\\
But nobody listens too much, don't you know?\\
I speak for the trees, and I'll yell and I'll shout\\
For the fine things on Earth that are on their way out!\\
They say I'm old-fashioned, and live in the past,\\
But sometimes I think progress is progressing too fast!\\
They say I'm a fool to oppose things like these,\\
But I'm going to continue to speak for the trees!
** This Trope is portrayed negatively in "The Zax," from ''The Sneetches and Other Stories''; both Zax are too stubborn to step aside and let the other pass, and simply stand there for years, refusing to budge, until an entire city is built around them!
* DidntThinkThisThrough: From "Did I Ever Tell You How Lucky You Are?", there's poor Herbie Hart, who has taken his throm-dib-u-lator apart, and is trying to put it together.
* DownerEnding: ''The Lorax'' ends with [[spoiler:the forest gone, the animals gone, and the Lorax gone. Only the Once-ler remains, who regrets his actions. However, there is one ray of hope: UNLESS. If the boy can regrow the forest and protect it, maybe the Lorax will come back]].
* EarlyInstallmentWeirdness: Some of his earliest children's books, like ''The 500 Hats of Bartholomew Cubbins'' and ''The King's Stilts'', were written in prose rather than in rhyme. (This was also true of the sequel to the former, ''Bartholomew and the Oobleck'', although it was grandfathered in from its predecessor, since by the time the book was written, he had consistently switched to rhyme).
* EvilChancellor: Droon of ''The King's Stilts''. Well, more of a {{Jerkass}} Chancellor anyway.
* ExactlyWhatItSaysOnTheTin: The Pants-Eating Plants from ''Did I Ever Tell You How Lucky You Are?''
* ExtremeOmnivore: Again, the [[ExactlyWhatItSaysOnTheTin Pants-Eating Plants]].
* FantasticFlora: Much of his visual work incorporates bizarre-looking trees and shrubs, many of them inspired by RealLife exotic botanical species grown at the San Diego Zoo. Seuss spent much of his time there after settling in La Jolla.
* FantasticRacism: "The Sneetches" is a thinly disguised allegory on racism (or classism). It describes a conflict between two subgroups of the titular Sneetches, a race of bird-like humanoids. One group has stars on their bellies, and thinks themselves superior because of it, while the other group doesn't. The Aesop comes after a huckster with the unlikely name of "Sylvester [=McMonkey=] [=McBean=]" convinces those without stars to pay him to have stars added to their bodies. Then it's no longer so special, since everyone has stars, but [=McBean=] has a machine to remove them as well, for a modest consideration. The two groups proceed to repeatedly alter who has stars and who doesn't, along with which of the two conditions are more desirable. By the time [=McBean=] packs up his operation and leaves, they don't remember who had stars to begin with and who didn't, and thus abandon their prejudices as worthless.
* GetOut
** This is shouted by Mayzie in "Horton Hatches the Egg" when, after allowing Horton to sit on her egg because she's too lazy for that responsibility, the egg of his starts hatching:
-->"But it's MINE!" screamed the bird, when she heard the egg crack.\\
(The work was all done. Now she wanted it back.)\\
"It's MY egg!" she sputtered. "You stole it from me!\\
''Get off of my nest and get out of my tree!"''
** ''Marvin K. Mooney, Will You Please Go Now!'' is an entire story telling the main character this.
* GettingCrapPastTheRadar: Attempted. In his original draft of ''Hop on Pop'', he tried to sneak "contraceptive" into the words the kid lists off that he's learning about. However, his editor caught it and made him change it.
* TheGreatPoliticsMessUp: The animated version of ''The Butter Battle Book'', a Cold War allegory with a UsefulNotes/BerlinWall expy, aired four days after the real Berlin Wall fell.
* HappyBirthdayToYou: The Mandolin plays this briefly at the end of ''The Hoober-Bloob Highway''.
* HardWorkHardlyWorks: The old man in "Did I Ever Tell You how Lucky You Are" tells the kid about a ''lot'' of folks who work hard at crummy jobs. Ali Sard has to mow "quick-growing grass" in his stingy uncle's backyard, and paint flagpoles on Sundays to get by. Mr. Potter is an i-crosser-t-dotter who dots i's and crosses t's at an I and T factory. Then there's Professor [=DeBreeze=] who has spent 32 years trying to teach Irish ducks how to speak Jivanese. The worst example is probably the Hauch-Hauchers in Hauch-Hauch. One was told to watch a bee, but didn't do well, so another was told to watch ''him''. Then ''he'' didn't do so well, so another Haucher had to watch him, and so on, until all of them were watching each other.
* HistoryRepeats: Very subtly done in the title tale of ''Literature/YertleTheTurtleAndOtherStories.'' After Yertle is dethroned and sent tumbling down into the swamp mud, the turtles that had previously made up his throne are swimming happily in the pond, with their eyes closed... Except for Mack (whom the other turtles are swimming towards), who is sitting on Yertle's old "throne" and looking upwards towards the sky. Considering Seuss's background as a political cartoonist (and that he admitted the story is an allegory for Hitler), the implication isn't difficult to spot...
* HonorableElephant: Horton is always faithful, one hundred percent.
* HumansAreCthulhu: The protagonist of "What was I Afraid of?" from ''The Sneeches and Other Stories'' doesn't look human, but it's the same idea. He keeps running into a ghostly pair of Pale Green Pants which he is terrified of... Until the end, when he discovers that the pants are even ''more'' terrified of ''him''. (Unlike most examples of this Trope, the story has a happy ending, with the two of them coming to terms with the fears and becoming friends.)
* IGaveMyWord: See HonorableElephant above.
* IgnoredEpiphany: The Once-ler does this twice in the 1972 AnimatedAdaptation of ''The Lorax''. Once when the Bar-ba-Loots were sent away, and again when the Swomee Swans and Humming Fish leave. The latter instance segues into his rant from the climax of the book.
* KarmaHoudini: The makers of the ''Horton Hears A Who'' film note in the commentary that he "wasn't in the comeuppance business." In fact, with the exception of ''Yertle the Turtle'', the unwelcome guests in ''Thidwick the Big-Hearted Moose'', it's rare that ''any'' villain in any book gets what's coming to him or her. (Nothing happens to Mayzie for the cruel trick she plays on Horton, and Sylvester [=McMonkey=] [=McBean=] gets no comeuppance for conning the Sneeches. Of course, doing so would likely distract readers from the overall message.)
** His acceptation seemed to be [[HoistByTheirOwnPetard characters responsible for their own undoing]], such as Mayzie in ''Horton Hatches The Egg" and Yertle The Turtle.
* KneelPushTrip: In ''One Fish, Two Fish, Red Fish, Blue Fish'', a pair of fish do this to another fish while all three of them are underwater. The two doing the pushing are described as "very, very bad".
* TheMovie: ''How the Grinch Stole Christmas'', ''The Cat In The Hat'' (twice), ''Horton Hears A Who!'', ''The Lorax''
* ANaziByAnyOtherName: Well, ''Yertle the Turtle'' clearly wasn't one (and he wasn't truly evil, he was just greedy), but as [[WordOfGod Seuss himself said in an interview]], he ''was'' meant to be an allegorical stand-in for Hitler and those of similar philosophical bent.
* NonIndicativeName: ''Literature/TheresAWocketInMyPocket'' does not contain any Wockets in the book proper. There is one right on the cover, though.
* NoPronunciationGuide: Averted in a poem one of Seuss's friends wrote about it (This is from ''Dr. Seuss & Mr. Geisel: A Biography'')
-->I think that you are a duce\\
And you certainly shouldn't rejoice\\
If you're pronouncing it "soose"\\
The doctor pronounces it "soice".
* NothingIsScarier: The vug under the rug from ''Literature/TheresAWocketInMyPocket''. It is never shown, appearing only as a lump under a rug in a dark room, and the only detail the reader knows about it is that it's the only creature the narrator is afraid of. This character, along with the red under the bed, was scary enough to be scrapped from the 1996 reprint.
* OnlySixFaces: Even though the good Doctor is very good at defining characters, some of his male protagonists look remarkably similar to each other and to other characters, such as Herman "Butch" Stroodel of ''Daisy-Head Mayzie'' to the protagonist of ''Literature/TheresAWocketInMyPocket''.
** Mayzie herself looks similar to Sally from ''The Cat in the Hat''.
* ParentalBonus: The entirety of ''You're Only Old Once!''
* PosthumousCollaboration: ''Hooray for Diffendoofer Day!'', fleshed out by poet Jack Prelutsky and illustrator Lane Smith following Seuss's death.
* RainOfSomethingUnusual: In ''Literature/BartholomewAndTheOobleck'', the king tires of only rain, sun, fog, and snow coming from the sky, so he orders his wizards to come up with something new. Unfortunately what they create is basically a rain of glue, which nearly destroys the kingdom.
* RhymesOnADime
** PainfulRhyme: Don't have a rhyming word? [[PerfectlyCromulentWord Just make one up!]]
* RhymingWithItself: In ''Dr. Seuss' ABC'':
-->Painting pink pajamas.\\
Policeman in a pail.\\
Peter Pepper's puppy.\\
And now Papa's in the pail.
* SdrawkcabAlias: One of Seuss's pen names is [=LeSieg=], which is his real surname (Geisel) backwards. More than one child grew up grumbling about these other beginner books that didn't have cool Dr. Seuss artwork and to be shocked when they learned this when they were older.
* SnakeOilSalesman: Zigzagged with Sylvester [=McMonkey=] [=McBean=] in the Sneeches story. What he sells truly works and does exactly what he claims, but he cleverly uses his Star-On Machine and Star-Off Machine to milk the Sneeches for everything they've got, playing on their attitude towards those dumb stars.
* SneezeOfDoom: ''Because A Little Bug Went Ka-Choo!''. The whole thing escalates up to an entire town in absolute chaos because of that bug.
* SupremeChef: Assuming Peter T. Hooper, the protagonist of ''Scrambled Eggs Super'', was telling his sister the truth, he was willing to go to the ends of the earth to get the eggs to make the best scrambled egg dish ever.
* SurpriseCreepy: ''Thidwick'' ends in [[spoiler:the unwanted guests being made into taxidermy]].
* ThematicSeries: His ''Dr. Seuss'' books are all linked thematically but aren't typically in any sort of continuity.
* {{Tulpa}}: The Glunk, in "The Glunk that got Thunk", a short story in ''I Can Lick 30 Tigers Today! And Other Stories''. Literature/TheCatInTheHat's daughter uses her "Thinker-Upper" to bring a variety of usually cute and harmless thoughtforms into being temporarily. But one night ends up with a Glunk which promptly causes many problems such as racking up very large phone bills. She discovers that the Glunk cannot be UN-thunk by her alone and she and her brother have to cooperate to get rid of it.
* UnbrokenVigil: ''Horton Hatches the Egg.'' "I meant what I said, and I said what I meant. An elephant's faithful, one hundred percent."
%%* {{Utopia}}: The protagonist's destination in ''I Had Trouble in Getting to Solla Sollew''.
%%* WhiteAndGreyMorality / GreyAndGreyMorality
* WeirdWeather: ''Bartholomew and the Oobleck'' centres around a king who demands a new kind of weather of a group of wizards loosely attached to his court. [[GoneHorriblyRight He gets a rain of big balls of viscous goop called "oobleck" that rapidly floods the kingdom, trapping citizens and wildlife in its stickiness]], as his long-suffering page boy Bartholomew Cubbins attempts to convince him to admit it was a mistake.
