Radovan Vlajkovic (18 November 1922 – 12 November 2001) was a Yugoslav politician who served as Chairman of the Collective Presidency of Yugoslavia from 1985 until 1986.
It's so bitterly ironic that the root of Radovan is apparently "care." Although I am not from the Balkan Peninsula, I would imagine that this name is as unusable there as Adolf is in Europe and America. All I can think of is Radovan Karadžić and the atrocities he committed in the name of "ethnic cleansing."
To me, the second element easily looks like the Slavic passive voice suffix. So, the name Radovan is actually from the passive voice of the verb "radovati" meaning "to joy, gladden, make happy". The meaning of Radovan would be "one who brings joy".
