Vojtěch Šafařík

Vojtěch Šafařík (26 October 1829 in Újvidék, Bács-Bodrog County, Vojvodina, Hungary (today Serbia) – 2 July 1902 in Prague, Bohemia) was a Slovak chemist, specialising in inorganic chemistry. Šafařík was the son of Pavel Jozef Šafárik, a Slovak philologist and historian.

The crater Šafařík on the Moon is named after him, and so is the minor planet 8336 Šafařík (in conjunction with his wife).

In Göttingen, he was involved in the investigation of the reaction of metals with alkyl iodides and produced diethylmagnesium. He also worked on the chemical composition of platinum and vanadium catalysts, and on organometallic compounds (Grignard compounds). At the Vienna Academy he published a work on physical chemistry. He also studied mineralogy.

In 1859, together with fellow chemist Antonín Bělohoubek, he participated in a detailed chemical and microscopic analysis of the authenticity of the notorious Queen's Court (Dvůr Králové) and Green Mountain (Zelená Hora) manuscripts. Finding Prussian Blue (unknown until the 18th century) in the initialling of the manuscripts, which were purported to date from the 1200s, they came to the conclusion that the manuscripts were forgeries and literary hoaxes.

In 1860, Šafařík published the first introductory university textbook of chemistry in the Czech language (Základové chemie čili lučby). He worked to improve Czech chemical terminology, building on and improving over the nomenclature of Czech chemist Jan Svatopluk Presl and the linguist Josef Jungmann. In 1882 he was appointed as the first professor of chemistry at Charles-Ferdinand University in Prague.

In later life, he wrote many popular textbooks as well as making over 20,000 observations of variable stars. His wife and co-worker Paulína Šafaříková was interested in the history and popularisation of astronomy.
