About August Freund
- August Freund (30 July 1835 – 28 February 1892) was an Austrian chemist who in 1881 first synthesised cyclopropane. Freund was born in 1835 in the town of Kety, Austria-Hungary.
- (The town now lies in Poland.) After graduating from the gymnasium (an advanced secondary school) in Cieszyn (then in Austria-Hungary, now on the Polish border with the Czech Republic), he studied pharmacy in Lviv (then in Austria-Hungary, now in Ukraine) and then in Leipzig, Germany.
- After studying at Lviv University from 1856-1858, he received a master's degree in pharmacy.
- He then assisted professor Leopold von Pebal in his investigations of petroleum.
- By 1861, he was teaching at a gymnasium in Ternopil (then in Austria-Hungary, now in Ukraine).
- By 1869, he was appointed a professor at the realschule (secondary school) in Lviv.
- He then began working towards a doctoral degree, receiving a doctorate from Leipzig University in 1871.
- In 1872, he became a professor of chemistry at the Lviv Technical University.
- There he investigated fermentation, petroleum, and ketones — among other subjects.
- He became dean of the Department of General and Analytical Chemistry, and from 1878, dean of the Department of Technical Chemistry.
- He was elected rector of the Polytechnic three times.In 1881 he discovered a method for synthesising cyclopropane: he treated 1,3 - dibromopropane with sodium metal.
- The method now bears his name.
- He was able to synthesise enough cyclopropane to do several chemical reactions and derive from the results the three-membered ring structure of cyclopropane. He died in Lviv in 1892.
