Charles Willison Johnson

Charles Willison Johnson (October 26, 1863 – July 19, 1932) was an American naturalist who specialized in entomology (especially Diptera) and malacology, making significant contributions in both fields. He was a mentor and inspiration to many students and young scientists such as William J. Clench (who founded a publication named Johnsonia in his honor). Johnson was Curator of the Wagner Free Institute of Science, 1888–1903, then was Principal Curator at the Boston Society of Natural History, 1903–1932.
He assisted Henry Augustus Pilsbry with The Nautilus, an important American malacological publication. Although both were credited on the title page as “Editors and Publishers”, Johnson was the business manager and Pilsbry was the editor, with Johnson acting as editor when Pilsbry was on extended field expeditions.
