Alan Alexander Milne (known professionally as A. A. Milne; January 18th 1882 -- January 31st 1956), English writer of wide-ranging variety, now remembered almost entirely for four books of children's stories and poems, many featuring the character [[Franchise/WinnieThePooh Winnie-the-Pooh]]. The process had already begun within his lifetime, to his considerable annoyance.

He first came to fame as a humorist, and was a contributor to ''Magazine/{{Punch}}'' (as was the cartoonist E. H. Shepard, who went on to illustrate his ''Pooh'' books). He also achieved considerable success as a playwright, and wrote several successful novels. The detective novel ''The Red House Mystery'' was quite successful in its day, though now is mainly remembered for having been held up by Creator/RaymondChandler, along with ''Literature/MurderOnTheOrientExpress'', as an exemplar of ludicrous whodunnit plotting. Two of his short stories were adapted for ''Series/AlfredHitchcockPresents''.

He also served in the British infantry during UsefulNotes/WorldWarI, and fought in the trenches.
!!Works by A. A. Milne with their own trope page include:
* ''Literature/WinnieThePooh''
!!Other works by A. A. Milne provide examples of:
* ADayInTheLimelight: The poem "Buckingham Palace" in "When We Were Very Young" is centered entirely on Christopher Robin, with no sign of Pooh and co.
* AmateurSleuth: The protagonist of ''The Red House Mystery''.
* AnAesop: Spoofed in "Twice Times":
-->There may be a Moral, though some say not\\
I think there's a moral, though I don't know what.
* BookcasePassage: In ''The Red House Mystery'' the AmateurSleuth comes to the conclusion that there must be a secret passage from the eponymous Red House to a nearby pavilion. But where in the house does it start? Well, it had better not be in the servant's quarters, because he can't go there without raising suspicion. And the same goes for the master bedroom and other guests' bedrooms and so on. In the end, the only place where he can go look without looking suspicious turns out to be the library. So he looks in the library, and sure enough, there it is! Behind a bookshelf and all.
* CallARabbitASmeerp: Played for laughs in ''The Ugly Duckling''.
* EngagementChallenge: Parodied in ''The Ugly Duckling'' (in which the challenge is deliberately easy because the princess isn't a beauty and her parents don't want to have to turn down anybody willing to take her) and ''Once On A Time'' (in which the suitor knows an easy way to complete the task but decides to make it look difficult so as to impress the King).
* ExcuseQuestion: In the play ''The Ugly Duckling'', the law of the kingdom requires a suitor for the hand of the princess to answer a riddle. The current princess is very plain, and her parents, not wanting to give anyone an excuse to turn her down, use riddles like "What is it which has four legs and barks like a dog?" This is PlayedForLaughs in multiple ways. Early in the play, the king and queen recall one suitor who was so desperate not to marry the princess that he somehow completely failed to answer the riddle. Later, a none-too-bright prince [[spoiler:who's an impostor anyway]] is given the answer in advance, but the riddle is changed at the last minute and he gets it wrong. Another character ([[spoiler:the real prince]]) quickly covers for him.
* FracturedFairyTale: ''The Ugly Duckling'', ''The Princess Who Would Not Laugh,'' ''Prince Rabbit,'' ''Once On A Time,'' and many others.
* HenpeckedHusband: The king in ''The Ugly Duckling''.
* JustTheIntroductionToTheOpposites: "Disobedience"
* PlayingCyrano: In ''The Ugly Duckling'', the hero and heroine ''both'' use one.
* SleepingDummy: In ''The Red House Mystery'', [[AmateurSleuth Anthony]] and [[TheWatson Bill]] do this before going off to tail a suspect at night, so that the suspect (who is staying in the same house as they are) won't realize they're onto him. Bill is pretty proud of his sleeping dummy, but Anthony's is so convincing that it even fools Bill.
* TwoPersonLoveTriangle: in ''The Ugly Duckling''
* TheWatson: Heavily lampshaded in ''The Red House Mystery'', where the AmateurSleuth Anthony outright asks his friend Bill to play Watson to his Holmes, specifically defining Bill's role as asking stupid questions and needing even the most obvious things explained to him. And indeed, this is what Bill does -- but half the time he's asking the questions because Anthony tells him to rather than because he's actually incapable of figuring out the answers, and sometimes he gets fed up with his friend's Sherlockian pretensions.
