Except that in the DnD Conan module, his class in not Barbarian at all you noob...
Barbarians didn't exist as a class in Gygax's D&D, this is why Minsc is a ranger.
It did, it started in Unearthed Arcana in 1E AD&D. Unearthed Arcana was written by... Gary Gygax.
2E AD&D didn't include Barbarians until later and wasn't technically "Gygax's D&D".

But, yes, a barbarian class did not exist in the AD&D 1st edition core rulebooks, which is why Gary Gygax proposed one in a Dragon Magazine article "The Big, Bad Barbarian" (issue #63, July 1982) and then incorporated a revised version into the new rules provided by the Unearthed Arcana hardcover book in 1985. See also "The Barbarian Cleric" by Thomas Kane (Dragon Magazine #109, May 1986) and "Tracking down the Barbarian: Creating Better Barbarians for AD&D 1st Edition Games" by David Howery (Dragon Magazine #148, August 1989).
AD&D 2nd edition did not include Gygax's barbarian class, though the very first book in the long-running Player's Handbook Rules Supplement series (PHBR), the Complete Fighter's Handbook, introduced the concept of class-based "kits" that provided a bit of customization relative to a base class, and those kits for fighters included barbarian, amazon, berserker, savage, and wilderness warrior entries.
The 14th book in the PHBR series, The Complete Barbarian's Handbook, introduced a barbarian fighter class and a shaman class, with new kits and other information. That was released in 1995, six years after the core rulebooks for AD&D 2nd edition in 1989, with the Complete Fighter's Handbook having been published later that same year.
Gary Gygax's article "Conan!" appeared in Dragon Magazine #36, April 1980, predating all of this.
