happy hour?

does anyone know where and when the phrase “happy hour” originated?

Well, since drinks are generally cheaper or free (male or female), you could get more drinks, so during this hour you could get shit-faced, and a lot happier…I think…

Of course, it was capitialized on, and made into happy-half-the-night, but that’s another story…

well, I mean, how did it start? who started it, when, why, all that? someone I know thinks they know, and I’d love to prove them wrong.

The Oxford English Dictionary’s first citation is from the Providence Journal in 1961

It may be related to “happy” as in “slightly drunk” (used in this sense since 1770). But the phrase was used in the sense “propitious moment” or “pleasant sixty minutes” for centuries before that.
