Observations of OB and Wolf-Rayet stars showing them to be unexpectedly strong sources of X-ray and radio radiation are discussed. Nonthermal radio emission shows the presence of relativistic electrons and magnetic fields far out in the powerful stellar winds that are characteristic of these stars. This suggests an alternative interpretation of the X-ray emission to Lucy and White's shock model as a result of the rapid Compton cooling that energetic electrons would suffer against photospheric radiation. It is proposed that it is the ubiquotous presence of relativistic electrons in early-type stellar winds that is the cause of both radio and X-ray emission and that magnetic reconnection in single and colliding pairs of winds may be the agent of the electron acceleration.
