Mendon was a male Benzite in the 24th century and an officer in the Benzite government. In 2365, he participated in an Officer Exchange Program operated between his government and the United Federation of Planets, with the rank of Ensign. Mendon specifically requested to be assigned to the USS Enterprise-D. He came aboard at Starbase 179. Mendon continued his analysis, and eventually found a solution, a tunneling neutrino beam. This saved both ships from destruction. (TNG: "A Matter Of Honor" )
