Otto Fred Hutter (born 1924) is an Austrian-born physiologist, Emeritus Regius Professor of Physiology at the University of Glasgow who is recognised as a passionate and innovative teacher. Born in Vienna, Otto Hutter was one of the hundreds of Jewish children evacuated to the UK in 1938 under the Kindertransport programme to escape the Nazi occupation. He did wartime work on the purification of penicillin and graduated with a BSc and PhD from University College London (UCL). He then continued at UCL as a researcher and then Lecturer in the Department of Physiology under GL Brown. Otto Hutter is renowned for his research in the fields of neuromuscular and synaptic transmission and cardiac and skeletal muscle physiology. His work (with Otto Trautwein) describing the cardiac pacemaker potential and its acceleration by adrenaline (in the tortoise sinus) and slowing by acetylcholine, and his own discovery of the increase in potassium permeability that underpins the latter, remain textbook findings. He is also acknowledged as an international authority on the movement of ion across membranes. In 2009 The Society launched the Otto Hutter Teaching Prize, to recognise outstanding teachers of undergraduate physiology and to raise the profile of physiology teaching.
