Father of Physiology


is the birthday of Albrecht von Haller, the father of experimental physiology. Haller, a Swiss biologist born in 1708, worked as a professor in Bern and Göttingen. He undertook myriad experiments, which he collected in his 1747 book First Lines in Physiology and a landmark eight-volume treatise, Physiological Elements of the Human Body, published between 1757 and 1766.

Haller discovered that some tissues react to stimuli, a phenomenon he divided into "irritability" (for muscles) and "sensibility" (for nerves). In his last years, he catalogued 52,000 publications about anatomy, botany, surgery, and medicine in a 20-volume bibliography. He died in December 1777.
