24988 Alainmilsztajn           Discovered 1998 June 19 by the OCA-DLR Asteroid Survey at Caussols.
Alain Milsztajn (1955-2007) was a particle physicist and astronomer who worked at the Service de physique des particles of the French Commissariat à l´énergie atomique at Saclay, where he specialized in the structure of the proton and in the search for Galactic dark matter using gravitational lensing.
