Wagner

From Memory Alpha, the free Star Trek reference

Professor Wagner was one of the lecturers at a psychology conference attended by several USS Enterprise-D crewmembers in 2369.

Deanna Troi and Data visited his phylobiology seminar with about 200 other Federation scientists, but according to Troi it was more than boring. Data, however, kept a full record of Wagner's lecture in his memory record. (TNG: "Timescape")
