11430 Lodewijkberg           Discovered 1960 Oct. 17 by C. J. van Houten and I. van Houten-Groeneveld at Leiden on Palomar Schmidt plates taken by T. Gehrels.
Lodewijk van den Berg (b. 1932) is the first Dutch-born citizen to participate in spaceflight. Born in Sluiskil, he was on Challenger flight STS-51B in 1985. As payload specialist he performed several experiments on crystals for the Spacelab 3 mission. The name was suggested by W. A. Fröger.
