Johann Vesling

Johann Vesling; Latin- Veslingius (1598-1649) was a German anatomist and botanist from Minden, Westphalia. In 1632 he became professor of anatomy and surgery at Padua, where he was an instructor to Thomas Bartholin. Early in his career, Vesling spent several years in Egypt, where he did extensive studies of the country's flora (particularly medicinal plants). Later in his career, he succeeded Alpino Alpini (died 1637) as director of the botanical garden at the University of Padua.

Vesling is remembered for the 1641 publication of Syntagma anatomicum publicis dissectionibus, in auditorum usum, diligenter aptatum, which was a popular textbook based on his anatomical disections in Padua. In this work he provided an early discussion of the human lymphatic system. Vesling also performed important studies of blood circulation, and was one the first physicians to describe the brain's circle of Willis.
