A method is investigated which enables exact solutions to be found for vacuum and radiation-dominated Friedmann universes of all curvatures in scalar-tensor theories with an arbitrary form for the coupling, [omega]([phi]), of the scalar field which determines the strength of the gravitational field. Particular classes of solution are presented for specific representative choices of [omega]([phi]), including the theories of Brans and Dicke, Barker, and Bekenstein, to illustrate the range of cosmological behaviors that are possible.
