  The capabilities of liquid argon time projection chambers (LArTPCs) to
reconstruct the spatial and calorimetric information of neutrino events have
made them the detectors of choice in a number of experiments, specifically
those looking to observe electron neutrino ($\nu_e$) appearance. The LArTPC
promises excellent background rejection capabilities, especially in this
"golden" channel for both short and long baseline neutrino oscillation
experiments. We present the first experimental observation of electron
neutrinos and anti-neutrinos in the ArgoNeut LArTPC, in the energy range
relevant to DUNE and the Fermilab Short Baseline Neutrino Program. We have
selected 37 electron candidate events and 274 gamma candidate events, and
measured an 80\% purity of electrons based on a topological selection.
Additionally, we present a of separation of electrons from gammas using
calorimetric energy deposition, demonstrating further separation of electrons
from background gammas.
