Doctor Ira Graves, PhD, was a male Human molecular cyberneticist in the 24th century. Graves was believed to be one of the finest scientific minds of his time and was a recipient of the Zee-Magnees Prize.

During his career, Graves had a lot of contact with Dr. Noonian Soong and claimed to have taught him everything he knew. When Graves met Soong's creation, Data, he suggested the fact that he educated Data's creator made him his "grandfather".

Late in his life, Graves retired to Gravesworld where he lived in virtual solitude, except for his assistant Kareen Brianon. His work continued there, and, by 2365, it had reached a critical stage. He had planned to transfer his consciousness into a computer.

Graves had also secretly fallen in love with Kareen, regretting the difference in their respective ages and finding himself too old for her.

Graves had began to suffer from Darnay's disease. He suspected an illness, but did not seek a doctor's help since he planned to survive through a computer. However, Kareen secretly signaled for help and Starfleet sent the USS Enterprise-D. He then met Data for the first time, and saw an unexpected opportunity to usurp control of Data's body, after which his original body died. His body was put into space in a torpedo casing.

Graves' essence existed in Data like a split personality exhibiting dominance over Data's. Although Graves initially tried to hide this fact, it quickly became apparent as his personality became unstable. After realizing that he had become a danger to others, Graves chose to leave Data's body and transfer himself to the Enterprise main computer. This allowed his vast knowledge to be stored permanently, although the Human element could not be salvaged.

Ira was fond of whistling the Tin Man's "If I Only Had a Heart" from The Wizard of Oz. (TNG: "The Schizoid Man")

Background information

Doctor Graves was played by W. Morgan Sheppard in his proper Human form and by Brent Spiner when Graves was in control of Data's body.

Graves' receipt of the Zee-Magnees Prize was not established in dialogue, but a certificate was seen in his laboratory. This was a reference to "The Ultimate Computer", where the prize was first mentioned.

The episode and the title were intended by the episode's writer Tracy Tormé as an homage to the British television series The Prisoner. One of the episodes in that series was titled "The Schizoid Man". During casting for the episode, the star of this series, Patrick McGoohan, was considered for the role of Dr. Ira Graves. (Star Trek Encyclopedia (4th ed., vol. 2, p. 256))

The computerized Ira Graves featured several in-jokes, including another reference to the Japanese series Dirty Pair in the form of "Kal(Yu/RJ) = DP (Angle)". (See 'Kei', 'Yuri', 'Dirty Pair', and 'Lovely Angels')

In the episode's script, Dr. Graves was a quantum physicist and was in his late seventies. [1]
