6769 Brokoff           Discovered 1985 Feb. 15 by A. Mrkos at Klet.
Father and son, Jan (1652-1718) and Ferdinand Maxmilian (1688-1731) Brokoff were prominent sculptors of the Baroque period in Bohemia. Their well known works include some of the statues on the Charles Bridge in Prague. The name was suggested by J. Ticha and M. Tichy.
