Ernst Hallier

Ernst Hallier (15 November 1831, in Hamburg – 19 December 1904, in Dachau) was a German botanist and mycologist.

As a young man he was trained as a gardener, later studying botany at the universities of Berlin, Jena and Göttingen. From 1858 he served as an instructor at the Pharmaceutical Institute in Jena, where in 1860 he obtained his habilitation. In 1865 he became an associate professor, resigning his professorship 19 years later (1884).

Hallier claimed that many diseases were caused by fungi including cholera, typhoid and measles. He claimed that he had extracted the causal fungi from patients but other scientists found that this was merely a case of external contamination. His work was subsequently largely discredited after it was criticized by Heinrich Anton de Bary. In 1869 he founded the journal ''Zeitschrift für Parasitenkunde.'' Provided by Wikipedia
