Commander Bruce Maddox was a male Human 24th century Starfleet cyberneticist. He worked in the Cybernetics Division of the Daystrom Institute and, in 2365, was the Associate Chair of Robotics.
In 2341, he was consulted in Starfleet Academy admissions. He was the only person to object to Data's entry on the grounds that, as an android, Data did not qualify as a sentient being.
Ever since learning about Data and Doctor Noonian Soong's work, Maddox was inspired to continue it. He followed Data's career remotely while he worked on his in cybernetics. He dreamed of creating more androids to help Starfleet in dangerous situations.
In 2365, Maddox earned Admiral Nakamura's support on a proposal to disassemble and reverse-engineer Lieutenant Commander Data in order to gain the final piece of knowledge he needed. After presenting his proposal to Captain Jean-Luc Picard, Commander William T. Riker and Data, Data studied Maddox' proposal and found it to be flawed in its ability to preserve the nuances of his positronic brain, prompting Maddox to assert his authority and order Data to submit by transferring him from USS Enterprise-D to Maddox' command aboard Starbase 173.
Bruce Maddox was played by Brian Brophy.
In Articles of the Federation, Maddox, now a captain, argues before Federation President Nan Bacco and the Federation Judiciary Council that B-4 should not be disassembled. He was successful in his arguments against Doctor Lars Patek, and B-4 remained in the custody of Maddox and the Daystrom Institute.
