S2 "White Plume Mountain" by Lawrence Schick was TSR's ninth "Dungeon Module" (not counting the special collector's edition of "Lost Tamoachan"), and was originally made available for sale at Gen Con XII in August, 1979, (along with T1 "The Village of Hommlet").

You're the author of White Plume Mountain, which remains one of the most famous of all AD&D modules ever produced, both because of its many unique puzzles and traps, as well as the presence of magic sword Blackrazor. What were your inspirations in creating this adventure?
White Plume Mountain was written as a sample document to persuade TSR to hire me as a game designer. I just plundered all the dungeons I’d designed over the previous four years, took out the best bits, and cobbled it all together. It worked; TSR hired me, bought the scenario, and published it as a module without changing a word. I’m a little embarrassed to this day by Blackrazor, inasmuch as it’s such a blatant rip-off of Elric’s Stormbringer; I would not have put it into the scenario if I ever thought it might be published.

White Plume Mountain is located in the northeastern part of the Shield Lands, near the Bandit Kingdoms and the Great Rift (see WORLD OF GREYHAWK, available from TSR)
White Plume Mountain, 1979
Location of the city of Keraptis in the original "Known World" setting. (I'm not certain what the circular map symbol to the northwest represents.)
Given Schick's long history of collaboration with Tom Moldvay, it's perhaps not surprising that "White Plume Mountain" has a strong B/X vibe, having more in common with adventures such as X2 "Castle Amber" than other AD&D modules.
(I'd situate the adventure somewhere in the Republic of Darokin, or possibly the Broken Lands, if I were to use the Known World or Mystara setting).
Sequels and Derivative Works:
The original module was re-released in 1981 as a color version, with new front and back cover art (see also The Art of the Genre). The new version included a now iconic full-page map of White Plume Mountain and its environs,* by Erol Otus.
*a writeup for Dragotha, the "undead dragon" was published in Dragon #134 (June, 1988)
A sequel for 2e "Return to White Plume Mountain" by Bruce R. Cordell was released in 1999 as part of D&D's 25th anniversary, set 20 years after the original.
Cordell also wrote an RPGA adventure "Dragotha's Lair" (1999). Another adventure "Ex Keraptis Cum Amore" by Andy Miller was published in Dungeon #77 (November/December 1999).
The release of "Return to White Plume Mountain" coincided with a novelization "White Plume Mountain" (1999) by Paul Kidd.
A d20 version by Andy Collins, Gwendolyn F. M. Kestrel, and James Wyatt, using material from the "Weapons of Legacy" system, was published in 2005. This was followed by a d20 supplement "Outside the Mountain is just as Dangerous as Inside" by Robert Wiese.

A 5e version was published in the "Tales from the Yawning Portal" collection (2017).
