The Barbarian, which appeared in White Dwarf issue 4 December 1977, was written for OD&D. It was many years before the "official" AD&D Barbarian was published, and Brian's class was very popular (being reprinted in The Best of White Dwarf Articles Volume 1, and even translated into Italian as part of "The Blue Book"). It is a very atmospheric class, with great abilities including Fearlessness (Fear instead makes them go beserk) and Sensing Danger, whereas the Unearthed Arcana version is rather bland.
But furthermore Brian's Barbarian also had something which the official AD&D version never had - it's own dedicated scenario.
