  We report on the discovery of high-energy (HE; E > 0.1 GeV) and very
high-energy (VHE; E > 100 GeV) gamma-ray emission from the blazar RBS 0413 with
Fermi Large Area Telescope (LAT) and VERITAS. The spectral energy distribution
(SED), including contemporaneous X-ray and optical observations, is presented.
Synchrotron self-Compton, external-Compton and lepto-hadronic models are
applied to the SED and the results are discussed.
