Hans Ris (June 15, 1914 – December 29, 2004) was an American zoologist and electron microscopist. His studies of chromosome structure revealed the importance of non-histone proteins. He was one of the first to recognize that blue-green algae were a special type of bacteria. He coined the term genophore for prokaryote DNA to highlight its differences from the eukaryal chromosome.[1] Hans Ris was a founding member of the ASCB and received the Distinguished Scientist Award by the Microscopy Society of America in 1983.
