54820 Svenders           Discovered 2001 July 11 by J. Dellinger and W. G. Dillon at the George Observatory, Needville.
Sven Treitel (b. 1929) and Enders Robinson (b. 1930) co-authored a landmark series of papers that founded the modern field of applied geophysical signal analysis. This followed Robinson's first performance of signal processing on a general-purpose digital computer.
