Keyboard order

I always wonder, who create the order of keyboard letters? why it was created such that? why doesn't it just follow the alphabetical order? if it's to make typing faster, then what if we're typing in other language, does it still retain the same speed? then why the combination of letters was arranged in three lines, not one, two, four and so on?

Jgn biarkan diri diselubungi misteri, just ask wikipedia. *sigh*
