Born in Ribe, he financed his education by writing novels. He was awarded a gold medal in 1876 for an essay on fungi, titled De danske Gjødningssvampe.[1] During his days as a university student in Copenhagen, he worked as an unpaid assistant to zoologist Japetus Steenstrup (1813–1897). In 1876, with Alfred Jørgensen (1848–1925), he published a Danish translation of Charles Darwin’s "The Voyage of the Beagle"; Rejse om Jorden. From 1879 to 1909, he was director of the physiological department at Carlsberg Laboratory.[2]
Hired by the Carlsberg Laboratory in Copenhagen in 1879,[3] he became the first to isolate a pure cell of yeast in 1883, and after combining it with a sugary solution, produced more yeast than was in a yeast bank. It was named as Saccharomyces carlsbergensis after the laboratory, and is the yeast from which are derived, all yeasts used in lager beers.[4] See Fermentation, Yeast.
Hansen is the taxonomic authority of the fungal genus Anixiopsis (1897) from the family Onygenaceae.[5]
He was honoured in 1911, when botanist H. Zikes published Hanseniaspora, which is a genus of yeasts.[6]
