136666 Seidel           Discovered 1995 Sept. 17 by M. Tichy and J. Ticha at Klet.
The work of Cesky Krumlov photographers Josef Seidel (1859-1935) and his son Frantisek (1908-1997) depicts both people and places of the southeast part of Sumava. The preserved archive of negatives opens a window into the first half of the 20th century, including Czech-German connections.
