24945 Houziaux           Discovered 1997 June 7 by E. W. Elst at the European Southern Observatory.
Léo Houziaux (b. 1932), a Belgian astrophysicist at Liège University, specialized in stellar structure at Mt. Wilson and Palomar. From rockets and satellites, he obtained the spectra and fluxes from over 30\,000 stars. He created the Department of Astrophysics at Mons University (B) in 1982.
