Gustav Heinrich Otth

Gustav Heinrich Otth (2 June 1806, in Bern – 8 November 1874) was a Swiss mycologist and military officer. Born in Bern to a family originally from Basel, Otth began his career in the military, serving in Swiss regiments in the Netherlands and Naples where he achieved the rank of captain-adjutant-major and was decorated for bravery. Following his retirement from military service in 1850, he turned to natural history and mycology, making contributions to fungal taxonomy despite lacking formal scientific training. His meticulous drawings, precise descriptions, and extensive herbarium specimens, primarily of fungi from the Bern and Thun regions, became valuable resources for mycological research and gained posthumous recognition in the scientific community.

Early life and military career

Otth was born into a Bernese family originally from Basel, on 2 June 1806. His father, Karl Emanuel Otth, held the office of city accountant in Bern. Gustav Otth initially pursued a military career, beginning as a second lieutenant in Bernese infantry in 1824. He later served in the Swiss regiments in the Netherlands and Naples, advancing to the rank of captain-adjutant-major. During his service, Otth participated in several battles, including the barricade fighting in Naples and campaigns in Messina and Catania, where he was wounded and later decorated for bravery. Disillusioned by political changes in Naples, Otth retired from military service in 1850 and returned to Switzerland.
