Huh? Barbarians existed in every edition, and Sorcerers existed in 4e as well as 3e and 5e.
In every edition that had a PH, but not in every PH1. Prior to 5e, the Sorcerer & Barbarian appeared in the 3.0/3.x PH1's, only. The Warlock & Warlord, only in the 4e PH1. The Illusionist & Assassin (as sub-classes) and psionics (as a non-class appendix) only in the 1e PH.
Rangers are broken in to spell casting and non-spell casting versions. Essentials gave us both in that one was using the primal power source and the other the martial. Technically a class called "ranger" was in each edition.
I suppose it's worth quibbling with this one, too. The 4e PH1 Ranger was a non-spell-casting implementation. The Essentials Ranger sub-classes, Scout and Hunter, were
both part-Primal casters.
The original 0e/1e Ranger didn't get spells until about name level, though, FWIW.
If you look beyond PH1s, there was a non-casting Ranger (and Paladin) in 3.5, and there was an all-Primal casting Archer, in the PH3, called the Seeker.
I disagree. Essentials came out as a core rule book with 2 additional rulebooks to present those 8 classes.
Essentials was not considered when the "in a prior PH1" idea was floated by MM going into the Next playtest, so take it up with him.
The context is "as a PHB1 class". I'm listing classes that came out in the initial PHB of each edition.
Which excludes Essentials, 0e, and B(/X)ECMI, since they lacked a PH.
