12008 Kandrup           Discovered 1996 Oct. 11 by T. B. Spahr at Catalina.
An exceptional researcher, teacher and mentor at the University of Florida, Henry E. Kandrup (1955-2003) will be remembered for his dedication to students. His eccentric and energetic lecturing style and love of nonlinear dynamics are now reflected in his celestial namesake, an unusual minor planet on a chaotic trajectory.
