Maximilian Ruppert Franz von Frey was an Austrian physiologist who studied the sense of touch, providing the first comprehensive information about the cutaneous senses. He confirmed the existence of locations for heat, cold, pressure, and pain reception and studied differential sensitivities to each. He suggested a sensory receptor for each modality but later work showed these identifications to be incorrect.
