Rudolf Höber (1873-1953) was a prominent physiologist who conducted pioneering research into the electro-chemical properties of cell membranes. As an instructor at the University of Zurich, later a professor at the University of Kiel and head of the Physiological Institute there, and finally as a Professor at the University of Pennsylvania, he introduced many young doctors to the science of physiology.
Rudolf already became interested in biological science as a child, and started the serious study of microorganisms as a teenager. His notebook contains 83 meticulously detailed drawings of amoebae, paramecia, hydrae and the like. This notebook is a beautiful art object as well as a record of his studies. The image above is of one double page of that notebook, which Rudolf drew at the age of about seventeen.
