An experimental program to demonstrate a novel phase space manipulation in which the horizontal and longitudinal emittances of a particle beam are exchanged has been completed at the Fermilab A0 Photoinjector. A new beamline, consisting of a TM₁₁₀ deflecting mode cavity flanked by two horizontally dispersive doglegs has been installed. We report on the first direct observation of transverse and longitudinal emittance exchange: {l_brace}{var_epsilon}ₓⁿ, {var_epsilon}{sub y}ⁿ, {var_epsilon}{sub z}ⁿ{r_brace} = {l_brace} 2.9 ± 0.1, 2.4 ± 0.1, 13.1 ± 1.3{r_brace} → {l_brace}11.3 ± 1.1, 2.9 ± 0.5, 3.1 ± 0.3{r_brace} mm-mrad.
