Franz Josef Ruprecht (born 1 November 1814 in Freiburg im Breisgau; deceased 4 April 1870 in St. Petersburg) was an Austrian-born physician and botanist active in Russia, where he was known as Frants Ivanovič Ruprekt (Russian: Франц Ива́нович Ру́прехт). He grew up, studied, and graduated as Doctor of Medicine in 1836 in Prague. After a short stint in medical practice in Prague, he was appointed curator of the herbarium of the Russian Academy of Sciences in St. Petersburg in 1839, then assistant director of the St. Petersburg botanical gardens between 1851 and 1855, and professor of botany in 1855 at the University of St. Petersburg.[1]
He described many new plants collected in the Russian Far East, including Alaska, then under Russian rule; examples include Adiantum aleuticum, Lonicera maackii, and Phellodendron amurense.
The genus Ruprechtia is named after him.[2]
