We have observed c baryons in nonresonant e+e- annihilation at energies around s=10.5 GeV through their decay to ++-. We measure the branching fraction to be (2.8 0.7 1.1)%. The momentum spectrum of the c is similar to that of charmed mesons, providing a constraint on models of charmed-quark hadronization.
