I think it was inevitable that this thread would end up being a list of people's favourite bassists. There are certainly plenty of really fine players listed here. But on reflection (admittedly not knowing the standard of sprogs's friend's daughter, or what is meant by "studying bass at college") I think the important thing is to learn which notes make up which types of chords, how the chords go together in sequences and which patterns you can use to get these in different places on the neck and in different keys. Listen carefully to your theory/harmony teacher, if you've got one (if not, get one, or a good book). Obviously, listen to lots of music. But it's much more satisfying (and instructive) to be able to say, "Hey, Pino's playing the 3 and 5 of the opening chord, with no root!" on his stand out intro to Paul Young's version of "Wherever I Lay My Hat" than to have to look up the TAB of aome dubious transcription on the net.
Sorry if that sounds didactic (I'm a didact). There are some great players in these posts - but study will help her appreciate them more - and emulate them quicker!
Just a lollipop to finish with: I'd like to mention the sadly short-lived Bill Black (of Combo fame, my Lord) and especially his stand up playing on Otis Blackwell's Don't Be Cruel in the recording by Elvis.
