(1873-1961) German physiologist whose work on the nervous system established that a chemical substance is responsible for the stimulation of one nerve cell (neuron) by another.
The substance was shown by the physiologist Henry Dale to be acetylcholine, now known to be one of the most vital neurotransmitters. For this work Loewi and Dale were jointly awarded the 1936 Nobel Prize for Physiology or Medicine.
