A Human psychiatrist, Dr. Elizabeth Dehner boarded the U.S.S. Enterprise NCC-1701 at the Aldebaran Colony in 2265 on an assignment to study crew reaction in emergency conditions. Highly rated on ESP tests, Dr. Dehner was born on Stardate 1089.5 in the town or city of Delman. Her father was Gerald Dehner.

At age 21, when the last ESP test on file in the Enterprise computer was performed, Dehner was 5’2″ tall and weighed 116 pounds. Her esper rating was 089. Her aperception quotient was 20/100. Her Duke-Heidelberg Quotient was 258, and her General Knowledge Quotient was 654895-109. According to her test, “Esper rating and quotients are better than average in all categories. Subject officer’s history indicates an esper orientation pattern since childhood, evidenced in superiority at ‘guessing games,’ reading cards, et cetera. Esper-orientation and abilities areevident through both the maternal and paternal bloodlines, but in only one case does the indicated tendency toward ESP go back more than three generations.

“Subject officer has been aware of the high ESP rating since secondary school days and it is, in part, the basis for interest and vocational training as a psychiatrist. Participation in tests and studies of other esper-oriented beings are the subject of a thesis now being published by this officer in association with the College of Medical Sciences of the Tri-Planetary Academy and was, in fact, the reason for this officer’s posting to the Aldebaran Colony.

“It must be stressed this officer’s interest in esperperception has been in relationship and pursuant to a vocation as a psychiatrist.”

Dehner argued that no action should have been taken against the rapidly mutating Gary Mitchell, as she believed that “a mutated, superior man could be a wonderful thing; a forerunner for a better kind of human being.” Dehner later began to mutate as well, and sacrificed her own life to stop the rampaging Mitchell. Captain Kirk recorded that she “gave her life in the performance of her duties.”[1]
