16706 Svojsík           Discovered 1995 July 30 by P. Pravec at Ondřejov.
Antonín Benjamin Svojsík (1876-1938) founded the Czech Boy Scout organization "Junák" in 1912, led it from 1914 until his death and was a member of the executive committee of the world Scout movement. After repeated bans between 1939 and 1989, "Junák" is now the most popular Czech children's organization.
