Species Vieusseuxia pavonia

For Gaspard Vieusseux (1746–1814), Swiss botanist and physician. After qualifying in Leiden in 1766, he completed his studies in Vienna, Strasbourg, Paris, London and Edinburgh, and opened a practice in Geneva. In 1771, he opened an office in Geneva. His first major publication, Traité de la Méthode Nouvelle d’Inoculer la Vérole Pepite earned him honours not only in Switzerland, but also in France, England and Sweden. He was the first physician to describe, in 1805, during an outbreak in Geneva, cerebrospinal fever or brain fever, subsequently called meningitis (meningococcal disease). He also gave an early account of Wallenberg’s Syndrome in 1810.
