30307 Marcelriesz           Discovered 2000 May 2 by P. G. Comba at Prescott.
Marcel Riesz (1886-1969) was a Hungarian-born mathematician (and brother of Frigyes Riesz) who spent most of his working life in Sweden. He did research in convexity theory, linear operators, potential theory and partial differential equations.
