7699 Božek           Discovered 1989 Feb. 2 by A. Mrkos at Klet.
Josef Božek (1782-1835) was a clockmaker at Prague Klementinum College and a creator of astronomical timekeepers. He also constructed the first steam engines in Bohemia. His son Romuald (1814-1898) reconstructed the Astronomical Clock of Prague Old Town.
