Alisha - you'll get a ton of responses with widely varied photographers. Here's what I would suggest as a start (no particular order of importance, though I will list in order of personal favorites):
1) Henri Cartier Bresson (the one and only)
2) Brassai (no one else ever made night photographs like him)
3) Eugene Atget (no people in his street photographs; he used large format w/ time exposures. But they are sublime!)
4) Elliott Erwitt
5) Garry Winogrand (had an interesting philosophy about street photography. Shoot everything, whether or not there is anything worthwhile photographing (you can decide later); and get in people's faces, whether it pissed them off or not).
These are all B&W photographers. To my taste, street is more compelling in B&W, but that is only a personal preference.
