74824 Tarter           Discovered 1999 Oct. 12 by C. W. Juels at Fountain Hills.
Jill C. Tarter (b. 1944) searches for extra-terrestrial intelligence at the SETI Institute using radio telescopes while holding the Bernard M. Oliver Chair for SETI. Her career inspired Carl Sagan to write Contact. She has also encouraged thousands to assist SETI discovery using their home computers.
