Small-angle Bhabha scattering data recorded at the Z resonance and large-angle Bhabha scattering data recorded at View the MathML source by the L3 detector at LEP are used to measure the running of the effective fine-structure constant for spacelike momentum transfers. The results are α<SUP>-1</SUP>(-2.1 GeV<SUP>2</SUP>)-α<SUP>-1</SUP>(-6.25GeV<SUP>2</SUP>)=0.78±0.26 α<SUP>-1</SUP>(-12.25 GeV<SUP>2</SUP>)-α<SUP>-1</SUP>(-3434GeV<SUP>2</SUP>)=3.80±1.29 in agreement with theoretical predictions
