      abstract     = {The light emitted by all galaxies over the history of the
                      Universe produces the extragalactic background light (EBL)
                      at ultraviolet, optical, and infrared wavelengths. The EBL
                      is a source of opacity for $\gamma$ rays via photon-photon
                      interactions, leaving an imprint in the spectra of distant
                      $\gamma$-ray sources. We measure this attenuation using
                      {739} active galaxies and one gamma-ray burst detected by
                      the {\it Fermi} Large Area Telescope. This allows us to
                      reconstruct the evolution of the EBL and determine the
                      star-formation history of the Universe over 90\\% of cosmic
                      time. Our star-formation history is consistent with
                      independent measurements from galaxy surveys, peaking at
                      redshift $z\sim2$. Upper limits of the EBL at the epoch of
                      re-ionization suggest a turnover in the abundance of faint
                      galaxies at $z\sim 6$.},
