Albrecht Von Haller, a Swiss physiologist, born in Bern, Oct. 10, 1708, died there, Dec. 12, 1777. He studied theology at Tubingen, and medicine and natural sciences at Leyden, where he graduated in 1726. After having paid a prolonged visit to England and France, he studied the higher branches of mathematics in Basel under Bernoulli. His delicate health induced him to accompany his friend Johann Gessner to the Alps, where he gathered the materials for his great botanical work and one of his poems. In 1729 he returned to Bern, where he founded an anatomical theatre. In 1735 he was appointed physician of the city hospital and director of the city library, and in the following year professor of botany, medicine, surgery, and anatomy at the newly established university of Gottingen. He founded there many scientific and beneficent institutions, and in 1751 the royal academy of sciences, of which he became president for life. He was ennobled by the emperor Francis I., received complimentary invitations from Oxford,Utrecht, Halle, Berlin, and St. Petersburg, was appointed royal councillor and physician by the king of England, and member of the grand council of Halle. In 1753 he relinquished all his trusts, excepting the presidency of the royal academy, and spent the rest of his life in Bern, where he became chief magistrate. - Haller is regarded as the father of modern physiology.

He established scientifically a new law, referring the animal functions to two powers, irritability and sensibility. He had evolved this idea as early as 1739, and announced it in 1747, in his Prima Lineoe Physiologioe, and expounded his system in its entire comprehensiveness in his Elemen-ta Physiologioe Corporis Humani (8 vols., Lausanne, 1757-'66, with a posthumous supplement, 1782). Among his other works are Bibliotheca Botanica (2 vols., Zurich, 1771 - '2), Bibliotheca Chirurgica (2 vols., 1774-'5), Bibliotheca Ana-tomica (2 vols., 1774-7), and the first part of the Bibliotheca Medieinoe Practicoe (4 vols., Basel, 1770 - '87). His Icones Anatomical (7 vols., Gottingen, 1743-'6), which he himself regarded as one of his best works, contains 46 drawings of many of the organs, and particularly of the arteries. His activity was prodigious. Besides numerous contributions to German and French scientific periodicals, he wrote 12,000 reviews for the Commentarii Societatis Regioe Scientiarum Gottingensis, and many novels.

His best poems are "The Alps" and "On the Origin of Evil."
