I always considered "Alchemy" - or in 3.5 parlance, "Craft (Alchemy)" - to be as stereotypically Wizard-ly as Spellcraft. I can't think of a Wizard I've made, since 3.0 came out, who didn't have at least a few ranks of Alchemy.
And I don't recall Wizards being able to identify potions in 1E, not "by the book"; locally, it was the CLERICS who could identify potions ... not the Magic-Users.
