Robert H. Sanders is Professor Emeritus at the Kapteyn Astronomical Institute of the University of Groningen, the Netherlands. He received his PhD in Astrophysics from Princeton University under the supervision of Lyman Spitzer. After working at Columbia University and the National Radio Astronomy Observatory, he moved to Europe. He spent his career studying active galactic nuclei (in particular, the Galactic Center), on the hydrodynamics of gas in galaxies and, for several decades, on the problem of the 'missing mass' in astronomical systems. His previous books are The Dark Matter Problem: A Historical Perspective (2010) and Revealing the Heart of the Galaxy: The Milky Way and Its Black Hole (2013). See less
