11966 Plateau           Discovered 1994 Aug. 12 by E. W. Elst at the European Southern Observatory.
Joseph Antoine Ferdinand Plateau (1801-1883) was a Belgian physicist who stated the so-called "Plateau-problem". The proof of the existence of a minimal surface (of least area) bounded by a simple closed curve in space was solved in 1930 by means of variational analysis.
