Eric Hahn was a male human Starfleet officer in the 24th century. As of the year 2366, he held the rank of admiral, and was Superintendent of Starfleet Academy. Hahn tentatively admitted Wesley Crusher to the Academy, but rescinded the offer when Crusher failed to show up at the oral exams. Hahn regretted this outcome, and encouraged Crusher to apply again the following year. (TNG episode: "Ménage à Troi") He was the husband of Crystal Hahn, and a friend of Captain Jean-Luc Picard.
