AMMAN,' 'PAUL (1634-1691), German physician and botanist, was born at Breslau in 1634. In 1662 he received the degree of doctor of physic from the university of Leipzig, and in 1664 was admitted a member of the society Naturae Curiosorum, under the name of Dryander. Shortly afterwards he was chosen extraordinary professor of medicine in the above-mentioned university; and in 1674 he was promoted to the botanical chair, which he again in 1682 exchanged for the physiological.
