11384 Sartre           Discovered 1998 Sept. 18 by E. W. Elst at the European Southern Observatory.
Jean-Paul Sartre (1905-1980), French novelist and the exponent of Existentialism, used his pen his entire life for the defense of individual freedom and human dignity. His masterwork L´Etre et le Néant (1943) confronts "human consciousness" with "being". He won the 1964 Noble Prize for literature, but refused to accept it.
