24959 Zielenbach           Discovered 1997 Oct. 3 by A. Galad and A. Pravda at Modra.
A former rocket scientist, Bill Zielenbach (b. 1943) worked in the printing industry. Since retiring, he has returned to science, estimating masses for more than 100 main belt minor planets, using his nearly six dozen old Macs running continuously more than three years.
