An android created by Dr. Noonien Soong, Juliana was externally an exact physical copy of his late wife, and possessed her memories and personality. Soong created the android so that it had no idea of its true nature, believing itself to be the human Juliana. [1]
Juliana encountered the Enterprise-D crew in 2370, and was delighted to see Data. She spent considerable time reminiscing with him about his early years. Data was able to determine Juliana's android nature, although he decided to keep the secret from her. [1]
