In virtual Compton scattering an electron is scattered off a nucleon s
uch that the nucleon emits a photon. We show that these events can be
selected experimentally, and present the first evidence for virtual Co
mpton scattering from the proton in data obtained at the Stanford Line
ar Accelerator Center. The angular and energy dependence of the data i
s well described by a calculation that includes the coherent sum of el
ectron and proton radiation.
