Gillian Taylor, Ph.D. was the assistant director of the Cetacean Institute until 1986. Dr. Taylor was an expert in Cetacean Biology and was especially fond of two Humpback whales in her care, George and Gracie.
In 1986, Gracie became pregnant, and Dr. Taylor had to arrange for them to be released back into the wild due to the inability to keep them in captivity. When the time came for them to be released, Gillian was contacted by Admiral James T. Kirk, who had come back in time to secure humpback whales for transport back to the 23rd century where they would repopulate the species and make contact with the alien probe that was currently attacking Earth.
After rescuing the freed whales from a group of whalers, Taylor was transported back to the 23rd century along with George and Gracie, explaining that she had nothing in the present, and reasoning that the future would need somebody who actually knew something about whales. She was later assigned to a Federation science vessel shortly after her arrival to the 23rd century, in order to "catch-up" on the past 300 years. (Star Trek IV: The Voyage Home)
