Named in memory of Simon Stampfer (1790–1864), who despite his humble beginnings became an astronomer and a founding member of the Imperial Academy of Sciences in Vienna. He was the first, in 1851, to compute photometric diameters of minor planets on the basis of the mean albedo derived from observations of the satellites of the giant planets, and in 1862 he was the first to show that the revolution period of P/Swift-Tuttle {see also planets  (5035),  (5036), respectively} was somewhat in excess of a century.
