14149 Yakowitz           Discovered 1998 Sept. 17 by the Lowell Observatory Near-Earth Object Search at the Anderson Mesa Station.
Sidney Yakowitz (1937-1999), a professor in the systems and industrial engineering department of the University of Arizona from 1966 to 1999, wrote books on adaptive control, simulation and numerical methods. The name was suggested by former and current Hawthorne House planetary science residents.
