Emil Abderhalden was a Swiss biochemist and physiologist. His main findings, though disputed already in the 1910s, were not finally rejected until the late 1990s. Whether his misleading findings were based on fraud or simply the result of a lack of scientific rigor remains unclear. Abderhalden's drying pistol, used in chemistry, was first described by one of his students in a textbook Abderhalden edited.

Heinrich Rohrer was a Swiss physicist who shared half of the 1986 Nobel Prize in Physics with Gerd Binnig for the design of the scanning tunneling microscope (STM). The other half of the Prize was awarded to Ernst Ruska. The Heinrich Rohrer Medal is presented triennially by the Surface Science Society of Japan with IBM Research – Zurich, Swiss Embassy in Japan, and Ms. Rohrer in his memory. The medal is not to be confused with the Heinrich Rohrer Award presented at the Nano Seoul 2020 conference.
