20164 Janzajíc           Discovered 1996 Nov. 9 by J. Ticha and M. Tichy at Klet.
Jan Zajíc (1950-1969) was a Czech student who burned himself to death on 1969 Feb. 25 in Wenceslas Square, Prague, as a protest against the occupation of Czechoslovakia the previous August. His hope for a democratic Czechoslovakia came true some 20 years after his death.
