Aileen Scott

Aileen Scott was an engineer, born on Earth and active in the 23rd century.

In the late 2240s, she, her grandson Montgomery Scott, and Dr. Dimetrios Aiglekdos of Starfleet Academy developed a method of manipulating warp drive field geometries that would increase the maximum attainable velocity of then-extant starships. (Orion Press: "By the Back Door")
