Minor planet (21751) Jennytaylor was named in honor of Jennifer Taylor who placed second in the Environmental Science Category at the Intel International Science and Engineering Fair (ISEF) 2005 in Phoenix, Arizona. Her research focused on identifying the levels and potential sources of prescription antibiotic contamination in the Tennessee River in the Shoals, Alabama, area. This research was a continuation of her previous work presented at ISEF 2004 in which she detected multidrug resistant pathogens in that area of the Tennessee River.

This minor planet was discovered September 9, 1999, by the LINEAR program of the MIT Lincoln Laboratory.
