Johann Jacob Friedrich Wilhelm Von Parrot (1792–1841) studied medicine and natural science at the University of Dorpat in Russia (now in Estonia) and became a surgeon in the Russian Army in 1821. He experimented in barometry and magnetism, and popularised the pocket sundial. He became Professor of Physiology and Pathology in 1816–17 and of Physics in 1826 in Dorpat. He was the first person recorded as having climbed Mount Ararat, in the far east of Turkey, in 1829. In 1831 Carl Anton von Meyer gave Parrat's name to the plant genus parrotia persica. Only one species of this genus was known until recently, introduced to the United Kingdom in 1846 at Kew from the Imperial Garden at St Petersburg. It comes from the same family as the witch hazel, the Hamamelidaceae. (See Williams P. Parrotia persica. Hortus 2010;
