Taitt was born on Tau Ceti II in 2348 to parents George Taitt and Pearl Taitt. At Starfleet Academy she wrote her senior year thesis on Solar Dynamics. She graduated in 2369 and earned a prestigious posting as a science officer to the USS Enterprise-D. (ST video game: Starship Creator, TNG episode & novelization: Descent)
Six weeks into her commission, during an encounter with a faction of non-Collective Borg led by Lore, Ensign Taitt manned the tactical station under the command of Beverly Crusher. She hesitantly held her post, and under orders, established a frequency shift firing pattern on a Borg starship.
When Commander Crusher took the Enterprise, protected by metaphasic shielding, into a local star, it was Taitt's observations and expertise in Solar Dynamics that allowed her to use the ship's phasers to trigger a solar flare, destroying the Borg. Crusher christened the move the "Taitt Maneuver". (TNG episode & novelization: Descent)
