Minkowski was the son of Marie Johanna Siegel and physiologist Oskar Minkowski.[4][5] His uncle was Hermann Minkowski, a mathematician and one of Einstein's teachers in Zürich. Rudolph studied supernovae and, together with Walter Baade, divided them into two classes (Type I and Type II) based on their spectral characteristics.[6] He and Baade also found optical counterparts to various radio sources.
He headed the National Geographic Society – Palomar Observatory Sky Survey, a photographic atlas of the entire northern sky (and south to declination -22°) down to an apparent magnitude of 22.[2]
Together with Albert George Wilson, he co-discovered the near-Earth Apollo asteroid 1620 Geographos in 1951,[7] and he also discovered Planetary Nebula M2-9. He additionally discovered a correlation between the luminosity of early-type galaxies and their velocity dispersion,[8] which was later quantified by Faber and Jackson. He won the Bruce Medal in 1961.[2] The lunar crater Minkowski is named after him and his uncle. In the 1940's he created a catalog of nearly 200 planetary nebulae, including Minkowski 2-9,[9] and a dwarf galaxy near NGC 541, known as Minkowski's object, is named after him.[10]
