The Hans Ris Seminar Series hosted by the Laboratory for Optical and Computational Instrumentation at the University of Wisconsin-Madison honors American cytologist and pioneer electron microscopist Dr. Hans Ris (1914-2004), Director of the University of Wisconsin-Madison's Integrated Microscopy Resource (IMR) from 1969 until 1984.  Ris oversaw the installation of one of the nation's first high-voltage electron microscopes while at the University of Wisconsin-Madison. The microscope was housed at LOCI, formerly the High Voltage Electron Microscope Facility. Ris's studies of chromosome structure revealed the importance of non-histone proteins, and alongside colleague Lynn Margulis, Ris was one of the first to recognize that blue-green algae were a type of bacteria. Ris was a founding member of the American Society of Cell Biology and received the Distinguished Scientist Award by the Microscopy Society of America in 1983. Ris remained Emeritus Investigator of the IMR until his death in 2004, and is remembered for the integrity of his scientific career by his colleagues at the University of Wisconsin-Madison.
