Hugo Erdmann

Hugo Wilhelm Traugott Erdmann (8 May 1862 – 25 June 1910) was the German chemist who discovered, together with his doctoral advisor Jacob Volhard, the Volhard-Erdmann cyclization. In 1898 he was the first who coined the term ''noble gas'' (the original noun is in German).

Erdmann invented the name Thiozone in 1908, hypothesizing that S3 made up a large proportion of liquid sulfur.

In collaboration with Rudolph Fittig, Erdmann found that dehydration of γ-phenyl structural analog of isocrotonic acid produced α-naphthol, an observation that provided evidence in understanding the nature of naphthalene. Provided by Wikipedia
